Question

why does lithium show anomalous behaviour ?​

Answer 1

Hllo!!!!

↪↪ANOMALOUS BEHAVIOUR OF LITHIUM: Reasons for its abnormal behavior are mainly due to the following reasons: Lithium atom and its ion has very small size.

Answer 2

due to following reason lithium show anomalous behaviour :-

1. Extremely small size of lithium atom and its ion

2. Greater polarizing power of lithium ion (Li+) due to its small size which results in covalent character in its compounds

3. Least electropositive character and highest ionization enthalpy as compared to other alkali metals

Hope, this answers your question.
