Question

(a) Arrange the following as per the instructions given in the brackets
(i) Cs, Na, Li, K, Rb (Increasing order of metallic character)

Answer 1

Metallic character:-

• It is the ability or tendency of an element to lose electrons in order to form cations.
• Metallic character increases down the group and decreases across a period from left to right.
• Therefore increasing order of metallic character is $\mathrm{Li}<\mathrm{Na}<\mathrm{K}<\mathrm{Rb}<\mathrm{Cs}$
