Question

First member of each group of s- and p-block elements show anomalous behaviour. Illustrate with two examples.

Answer 1

Answer:

Your answer is here ✌️

First member of each group of representative elements (i.e, s- and p-block elements) shows anomalous behaviour due to i) small size, ii) high ionisation enthalpy, iii) high electonegartivity and (iv) absence of d-orbitals e.g. in s-block elements, lithium shows anomalous behaviour from rest of the alkali metals.
