What are the anomalous properties of lithium Class 11?
The anomalous behaviour of lithium is as follows:
- Lithium is harder than other metals of the respective group.
- It has higher Melting and boiling point than other metals.
- It is least reactive.

Is lithium and beryllium ionic?
Lithium belongs to the family of Alkali metals whereas Beryllium belongs to the family of Alkali Earth Metals. In order to form ionic bonds an atom must lose electron easily to become positively charged ion or Cation.The lesser the ionization enthalpy the easier it is to form a cation and thus ionic bond.
