Question

Give reason for formation of both oxide and hydroxides when metal reacts with water

Answer 1

In the presence of water and oxygen (or simply air), some elements— sodium—react rapidly, to give the hydroxides. In part, for this reason, alkali and alkaline earth metals are not found in nature in their metallic, i.e., native, form. ... The surface of most metals consists of oxides and hydroxides in the presence of air.
