The least active metals are found in nature as elements (native metals). When the least active metals are found as compounds, they can be extracted from their ores by heating in air (roasting in air). Moderately active metals can be extracted by heating their ores with a suitable reducing agent (thermal reduction).

It is somewhat decorative. It is easily formed, machined, and cast. Pure aluminium is soft and lacks strength, but alloys with small amounts of copper, magnesium, silicon, manganese, and other elements have very useful properties. Aluminium is an abundant element in the earth's crust, but it is not found .

Hydrogen is found in the largest amount in the water on the earth, despite its great abundance everywhere, hydrogen is very rare in the earth's atmosphere (less than 1 part per million by volume). Because when hydrogen enters in the atmosphere of earth, then due to light weight quickly escapes from the Earth's gravity into outer space .

Metal Analysis Just as one can identify a liquid by it's properties, one can also identify a metal by how it behaves. Of course we can not really use smell as a method of identification with a metal, but instead we can use how it reacts with other substances. We can not look at all of the metals. There just is not time.

Dec 04, 2009· Best Answer: This is my reasoning behind this question, hope it helps: The fundametal concept you have to know here is that elements like to have fully filled or halffilled orbitals. The easier it is for an element to get its valence orbitals filled or halffilled, the more likely it is to react. An ...
