Chemistry of Manganese

Manganese and Air. By its location on the periodic table, Manganese is a little less electronegative than its neighbors which makes it a little less reactive to air. Manganese metal has the ability to burn in the presence of oxygen to form Mn 3 O 4. 3Mn(s) + 2O2(g) → Mn3O4(s) 3 Mn ( s) + 2 O 2 ( g) → Mn 3 O 4 ( s)
