Difference Between Aluminum and Magnesium l Aluminum vs Magnesium


The key difference between aluminum and magnesium is that the aluminum is a corrosion resistant metal whereas magnesium is not.

Magnesium and aluminum are two chemical elements that we can categorize as metals in the periodic table. Both are naturally occurring metals in different mineral forms. There are many applications of these chemical elements as metals due to their favourable properties.

What is Aluminum?

Aluminum or Al is an element in group 3 and period 3 and has the atomic number of 13. The electron configuration of Al is 1s2 2s2 2p6 3s2 3p1. Moreover, it is a silvery white solid, and it is the most abundant metal in the earth crust. It is not soluble in water at room temperature.

Furthermore, the atomic weight of aluminum is 27 g mol-1, and it is a light weighted, durable metal. It doesn’t easily ignite. Also, since this metal is too reactive to stay in its free form, naturally it occurs in mineral forms. Besides, the main aluminum containing mineral is bauxite. Large bauxite ores are located in Australia, Brazil, Jamaica and Guinea. Also, aluminium is in the mineral forms such as cryolite, beryl, garnet, etc.
