Question

Arrange the following as per the instructions given in the brackets:

Cs, Na, Li, K, Rb ( Increasing order of metallic character).

Answer 1

• As we move down the group atomic radius increases because the number of shells increases.
• So, the metallic character also increases and the tendency to lose electrons also increases.
• Therefore, the increasing order of metallic order is: Li < Na < K< Rb < Cs.
