Question

Arrange the following alkali metals in the increasing order of their metallic nature:

• A. $Rb$
• B. $K$
• C. $Na$
• D. $Cs$
• E. $Li$

Answer 1

Higher the $EN$ value, lesser the metallic nature of an element.
Therefore, the elements in the decreasing order of $EN$ will have an increasing order of metallic nature.
That is, $Li,Na,K,Rb,Cs$
