Solution

The correct option is A
H

Metals are defined as the elements which form positive ions by the loss of electrons.Eg. Sodium, magnesium, aluminium etc.

Non-metals are the elements which form negative ions by the gain of electrons.Eg. Chlorine, nitrogen, oxygen etc.

Hydrogen is a non-metal which forms positive ions.
