Question

Why are metals unstable?

Answer 1

Hii..

here is your answer.

Due to the there large atomic size and small ionisation enthalpy they are unstable.

they have oxidation state +1 ..


It can accept more electron.

hope it helps you

Answer 2

• Most metals are chemically unstable, reacting with oxygen in the air to form oxides over varying timescales (for example iron rusts over years and potassium burns in seconds).

• The transition metals take much longer to oxidise (such as iron, copper, zinc, nickel).
