Why does Li show anomalous behaviour

Why does Li show anomalous behaviour
by

1 Answer

Answer :

This is due to the :

(i) Exceptionally small size of its atom and ion, and

(ii) High polarising power (i.e., charge/ radius ratio).

 As a result, there is increased covalent character of lithium compounds which is responsible for their solubility in organic solvents. And lithium shows diagonal relationship to magnesium .
