The alkali metals are paramagnetic but their salts are diamagnetic-why?

Text Solution

Verified by Experts

Due to the presence of an unpaired valence electron `(ns^1)`, the alkali metals are paramagnetic in nature. During salt ormatton, this unpaired electron of the outermost shell leaves the metal atom and becomes attached with a non-metal atom. As a result, the cation and the anion thus obtained contain no unpaired electron. Hence, the alkali metal salts are diamagnetic in nature.
