Question

Why sodium is less reactive than potassium

Answer 1

Thus, in potassium, the outermost electron is better shielded from the attractive force of the nucleus. It follows, therefore, that this outermost electron is more easily lost than it is in sodium, so potassium can be converted to ionic form morereadily than sodium. Hence,potassium is more reactive than sodium.

Answer 2

Sodium is less reactive than potassium because the atomic size of sodium is smaller than the potassium. Hence sodium has more greater electrostatic force of attraction between its electrons and nucleus. So , it less readily looses its electrons than potassium ...✌✌✌
