It''s Elemental - The Element Magnesium
Although it is the eighth most abundant element in the universe and the seventh most abundant element in the earth''s crust, magnesium is never found free in nature. Magnesium was first isolated by Sir Humphry Davy, an English chemist, through the electrolysis of a mixture of magnesium oxide (MgO) and mercuric oxide (HgO) in 1808.

Transition metals are defined as those elements that have (or readily form) partially filled d orbitals. As shown in Figure 1, the d-block elements in groups 3–11 are transition elements. The f-block elements, also called inner transition metals (the lanthanides and actinides), also meet this criterion because the d orbital is partially occupied before the f orbitals.
