Component and constituent refer to a part that goes into the making of a complete system or compound. Component often refers to one of a number of parts: a new component for the stereo system.
Constituent suggests a necessary part of the whole: The constituents of a molecule of water are two atoms of hydrogen and one of oxygen.
Ingredient is most frequently used in nonscientific contexts: the ingredients of a cake; the ingredients of a successful marriage.

Word Origin for element C from Latin elementum a first principle, alphabet, element, of uncertain origin. In fact, an aluminium bar held pride of place alongside the Crown Jewels at the Paris Exhibition, while Napoleon is said to have reserved aluminium tableware for only his most honoured guests.
It wasn't until that Charles Martin Hall, an uncommonly dogged, amateur scientist of 22, developed the first economic means for extracting aluminium.
Working in a woodshed with his older sister as assistant, he dissolved aluminium oxide in a bath of molten sodium hexafluoroaluminate more commonly known as 'cryolite' , and then pried the aluminium and oxygen apart using a strong electrical current.
It wasn't only the transportation industry that grasped aluminium's advantages. By the early s, aluminium had already supplanted copper in electrical power lines, its flexibility, light weight and low cost more than compensating for its poorer conductivity.
Aluminium alloys are a construction favourite, finding use in cladding, windows, gutters, door frames and roofing, but are just as likely to turn up inside the home: in appliances, pots and pans, utensils, TV aerials, and furniture.
As a thin foil, aluminium is a packaging material par excellence , flexible and durable, impermeable to water, and resistant to chemical attack - in short, ideal for protecting a life-saving medication or your favourite candy bar.
But perhaps aluminium's most recognizable incarnation is the aluminium beverage can, hundreds of billions of which are produced annually.
Each can's naturally glossy surface makes as an attractive backdrop for the product name, and while its thin walls can withstand up to 90 pounds of pressure per square inch three times that in a typical car tyre , the contents can be easily accessed with a simple pull on the tab.
There is, however, a darker side to this shiny metal. Despite its abundance in Nature, aluminium is not known to serve any useful purpose for living cells.
Humans don't require aluminium, and yet it enters our bodies every day - it's in the air we breathe, the water we drink, and the food we eat.
While small amounts of aluminium are normally present in foods, we are responsible for the major sources of dietary aluminium: food additives, such as leavening, emulsifying and colouring agents.
Swallowing over-the-counter antacids can raise intake levels by several thousand-fold. And many of us apply aluminium-containing deodorants directly to our skin every day.
What's worrying about all this is that several studies have implicated aluminium as a risk factor for both breast cancer and Alzheimer's disease.
While most experts remain unconvinced by the evidence, aluminium at high concentrations is a proven neurotoxin, primarily effecting bone and brain.
So, until more research is done, the jury will remain out. Now, perhaps that IS something to trouble your mind on your next long haul flight. Next week, talking of the way the elements sound, what about this one.
There aren't many elements with names that are onomatopoeic. Say oxygen or iodine and there is no clue in the sound of the word to the nature of the element, but zinc is different - zinc, zinc, zinc, you can almost hear a set of coins falling into an old fashioned bath.
It just has to be a hard metal. In use, zinc is often hidden away, almost secretive. It stops iron rusting, sooths sunburn, keeps dandruff at bay, combines with copper to make a very familiar gold coloured alloy and keeps us alive but we hardly notice it.
And you can catch up with the clink of zinc with Brian Clegg on next week's Chemistry in its element.

It is created almost entirely after fusion of carbon in massive stars that will later become Type II supernovae : this fusion creates 26 Mg, which, upon capturing free protons and neutrons becomes aluminium.
Some smaller quantities of 27 Al are created in hydrogen burning shells of evolved stars, where 26 Mg can capture free protons. However, the trace quantities of 26 Al that do exist are the most common gamma ray emitter in the interstellar gas.
Overall, the Earth is about 1. Because of its strong affinity for oxygen, aluminium is almost never found in the elemental state; instead it is found in oxides or silicates.
Feldspars , the most common group of minerals in the Earth's crust, are aluminosilicates. Aluminium also occurs in the minerals beryl , cryolite , garnet , spinel , and turquoise.
Although aluminium is a common and widespread element, not all aluminium minerals are economically viable sources of the metal.
Almost all metallic aluminium is produced from the ore bauxite AlO x OH 3—2 x. Bauxite occurs as a weathering product of low iron and silica bedrock in tropical climatic conditions.
The history of aluminium has been shaped by usage of alum. The first written record of alum, made by Greek historian Herodotus , dates back to the 5th century BCE.
The nature of alum remained unknown. Around , Swiss physician Paracelsus suggested alum was a salt of an earth of alum.
Attempts to produce aluminium metal date back to He reacted anhydrous aluminium chloride with potassium amalgam , yielding a lump of metal looking similar to tin.
As Wöhler's method could not yield great quantities of aluminium, the metal remained rare; its cost exceeded that of gold.
Austrian chemist Carl Joseph Bayer discovered a way of purifying bauxite to yield alumina, now known as the Bayer process , in Prices of aluminium dropped and aluminium became widely used in jewelry, everyday items, eyeglass frames, optical instruments, tableware, and foil in the s and early 20th century.
Aluminium's ability to form hard yet light alloys with other metals provided the metal many uses at the time. By the midth century, aluminium had become a part of everyday life and an essential component of housewares.
Throughout the 20th century, the production of aluminium rose rapidly: while the world production of aluminium in was 6, metric tons, the annual production first exceeded , metric tons in ; 1,, tons in ; 10,, tons in However, the need to exploit lower-grade poorer quality deposits and the use of fast increasing input costs above all, energy increased the net cost of aluminium;  the real price began to grow in the s with the rise of energy cost.
Aluminium is named after alumina, or aluminium oxide in modern nomenclature. The word "alumina" comes from "alum", the mineral from which it was collected.
The word "alum" comes from alumen , a Latin word meaning "bitter salt". British chemist Humphry Davy , who performed a number of experiments aimed to isolate the metal, is credited as the person who named the element.
In , he suggested the metal be named alumium in an article on his electrochemical research which was published in Philosophical Transactions of the Royal Society.
The -ium suffix followed the precedent set in other newly discovered elements of the time: potassium, sodium, magnesium, calcium, and strontium all of which Davy isolated himself.
Nevertheless, element names ending in -um were known at the time, for example, platinum known to Europeans since the 16th century , molybdenum discovered in , and tantalum discovered in The -um suffix is consistent with the universal spelling alumina for the oxide as opposed to aluminia ; compare to lanthana , the oxide of lanthanum , and magnesia , ceria , and thoria , the oxides of magnesium , cerium , and thorium , respectively.
In , British scientist Thomas Young  wrote an anonymous review of Davy's book, in which he objected to aluminum and proposed the name aluminium : "for so we shall take the liberty of writing the word, in preference to aluminum, which has a less classical sound.
It was subsequently suggested this was a typo rather than intended. Aluminium production is highly energy-consuming, and so the producers tend to locate smelters in places where electric power is both plentiful and inexpensive.
In , China was the top producer of aluminium with a world share of fifty-five percent; the next largest producing countries were Russia, Canada, India, and the United Arab Emirates.
According to the International Resource Panel 's Metal Stocks in Society report , the global per capita stock of aluminium in use in society i.
Bauxite is converted to aluminium oxide by the Bayer process. Bauxite is blended for uniform composition and then is ground.
The resulting slurry is mixed with a hot solution of sodium hydroxide ; the mixture is then treated in a digester vessel at a pressure well above atmospheric, dissolving the aluminium hydroxide in bauxite while converting impurities into relatively insoluble compounds: .
After this reaction, the slurry is at a temperature above its atmospheric boiling point. It is cooled by removing steam as pressure is reduced.
The bauxite residue is separated from the solution and discarded. After about half of aluminium has precipitated, the mixture is sent to classifiers.
Small crystals of aluminium hydroxide are collected to serve as seeding agents; coarse particles are converted to aluminium oxide by heating; excess solution is removed by evaporation, if needed purified, and recycled.
The liquid aluminium metal sinks to the bottom of the solution and is tapped off, and usually cast into large blocks called aluminium billets for further processing.
Anodes of the electrolysis cell are made of carbon—the most resistant material against fluoride corrosion—and either bake at the process or are prebaked.
The former, also called Söderberg anodes, are less power-efficient and fumes released during baking are costly to collect, which is why they are being replaced by prebaked anodes even though they save the power, energy, and labor to prebake the cathodes.
Carbon for anodes should be preferably pure so that neither aluminium nor the electrolyte is contaminated with ash.
Despite carbon's resistivity against corrosion, it is still consumed at a rate of 0. Cathodes are made of anthracite ; high purity for them is not required because impurities leach only very slowly.
Cathode is consumed at a rate of 0. A cell is usually a terminated after 2—6 years following a failure of the cathode.
Further purification can be done by the Hoopes process. This process involves the electrolysis of molten aluminium with a sodium, barium, and aluminium fluoride electrolyte.
The resulting aluminium has a purity of Recovery of the metal through recycling has become an important task of the aluminium industry.
Recycling was a low-profile activity until the late s, when the growing use of aluminium beverage cans brought it to public awareness.
White dross from primary aluminium production and from secondary recycling operations still contains useful quantities of aluminium that can be extracted industrially.
The process produces aluminium billets, together with a highly complex waste material. This waste is difficult to manage. It reacts with water, releasing a mixture of gases including, among others, hydrogen , acetylene , and ammonia , which spontaneously ignites on contact with air;  contact with damp air results in the release of copious quantities of ammonia gas.
Despite these difficulties, the waste is used as a filler in asphalt and concrete. Aluminium is the most widely used non-ferrous metal. Aluminium is almost always alloyed, which markedly improves its mechanical properties, especially when tempered.
The major uses for aluminium metal are in: . Several sulfates of aluminium have industrial and commercial application.
Aluminium sulfate in its hydrate form is produced on the annual scale of several millions of metric tons. Despite its widespread occurrence in the Earth's crust, aluminium has no known function in biology.
In most people, aluminium is not as toxic as heavy metals. Aluminium, although rarely, can cause vitamin D-resistant osteomalacia , erythropoietin -resistant microcytic anemia , and central nervous system alterations.
People with kidney insufficiency are especially at a risk. During the Camelford water pollution incident people in Camelford had their drinking water contaminated with aluminium sulfate for several weeks.
A final report into the incident in concluded it was unlikely that this had caused long-term health problems.
Aluminium has been suspected of being a possible cause of Alzheimer's disease ,  but research into this for over 40 years has found, as of [update] , no good evidence of causal effect.
Aluminium increases estrogen -related gene expression in human breast cancer cells cultured in the laboratory.
Exposure to powdered aluminium or aluminium welding fumes can cause pulmonary fibrosis. Food is the main source of aluminium.
Drinking water contains more aluminium than solid food;  however, aluminium in food may be absorbed more than aluminium from water. Consumption of antacids , antiperspirants, vaccines , and cosmetics provide possible routes of exposure.
In case of suspected sudden intake of a large amount of aluminium, the only treatment is deferoxamine mesylate which may be given to help eliminate aluminium from the body by chelation.
High levels of aluminium occur near mining sites; small amounts of aluminium are released to the environment at the coal-fired power plants or incinerators.
Acidic precipitation is the main natural factor to mobilize aluminium from natural sources  and the main reason for the environmental effects of aluminium;  however, the main factor of presence of aluminium in salt and freshwater are the industrial processes that also release aluminium into air.
Aluminium is primary among the factors that reduce plant growth on acidic soils. Sorghum is believed to have the same tolerance mechanism.
Aluminium production possesses its own challenges to the environment on each step of the production process. The major challenge is the greenhouse gas emissions.
The most potent of these gases are perfluorocarbons from the smelting process. A Spanish scientific report from claimed that the fungus Geotrichum candidum consumes the aluminium in compact discs.
Better documented, the bacterium Pseudomonas aeruginosa and the fungus Cladosporium resinae are commonly detected in aircraft fuel tanks that use kerosene -based fuels not avgas , and laboratory cultures can degrade aluminium.
