Aluminum is a very reactive metal that isn't commonly found in natural environments, because it reacts with Hydrogen, half of water, that changes aluminum to it's impurity.

What are the main health concerns of aluminum?
Excepting some very rare allergies aluminium is not dangerous.
Why aluminium is not extracted from alumina by pyrometallurgical operations?
aluminium has greater tendancy to bind to oxygen than carbon,so it cannot be extracted
Why are alloys so strong?
Alloys are so strong because they will take properties from both metals, such as when you alloy Titanium and Aluminium. Aluminium will get stronger because the forces that titanium once used to attract each other is now used to attract the aluminium
Why does electropositivity first increase from boron to aluminium and then decrease down the group?
Boron is a metalloid, while aluminium is a metal. The size of the aluminium atom is much greater than boron, so electropositivity increases from boron to aluminium. But then electropositivity decreases from aluminium to thallium due to the poor shielding effect of the d10 orbital.
Why is the frame on a bike made out of alloy and not pure aluminium?
Aluminium alloys are stronger than pure aluminium, which is comparatively soft. Pure aluminium is also considered chemically reactive (thus the layer of aluminium oxide which coats the metal due to oxidation). Pure aluminium hardly exists due to its strong affinity with oxygen in air. In fact, aluminium foils and beverage cans are also alloys of aluminium, with about 92 to 99% of aluminium. So likewise, bike frames are also made of alhminium alloys because of its characteristics of being strong and lightweight.
What elements in in aluminium?
Aluminium is actually an element, so the only element in aluminium is aluminium.
Rare dark blue to bluish-green mineral composed of magnesium and aluminium?
sapphirine Lalituchil
What are the main health concerns of aluminum?
Excepting some very rare allergies aluminium is not dangerous.
Is aluminium a living thing?
Aluminium is a metal, so is non-living.
How easily does aluminium erode?
Aluminium is not a hard metal so the erosion is very possible.
What are substances which are rich in aluminium?
Aluminium is the third most abundant element on earth, it is highly reactive so is very rarely found as pure aluminium. It is found in concentrated levels in bauxite, which is mined and then refined into aluminium
How many protons does an aluminum atom contain?
The atomic number of aluminium is 13. So there are 13 protons in aluminium.
Why do hangings on sails have anodized aliminium?
Aluminium contains harmful compounds , so in case aluminium reacts with skin it is anolized.
Why aluminium is not extracted from alumina by pyrometallurgical operations?
aluminium has greater tendancy to bind to oxygen than carbon,so it cannot be extracted
Why are alloys so strong?
Alloys are so strong because they will take properties from both metals, such as when you alloy Titanium and Aluminium. Aluminium will get stronger because the forces that titanium once used to attract each other is now used to attract the aluminium
Why was aluminium rare during Napoleonic times?
Aluminium is produced by electrolysis of the mineral bauxite. In Napoleonic times there was no cheap electricity :P Aluminum metal was rare because the Hall-Heroult process of running electricity through molten cryolite had not been discovered yet. Aluminum could only be produced with very small yield before this. Aluminum compounds such as bauxite are plentiful, but it is incredibly rare to find ores containing elemental aluminum.
Why was aluminium more expensive in the 1850s?
Aluminium is a reactive metal and so is hard to extract from it's compounds without modern technology.
