Question

Alkali metals are part magnetic but their salts are diamagnetic why

Answer 1

Answer:

Explanation:

Magnetism depends upon number of unpaired electron. So if the ion contains all paired electron the spin motion is cancled( as a pair has 2 electrons 1 of them has +1/2 value and another has -1/2 value and together their sum is 0), hence they are dimagnetic in nature.
