Question

Why does s block elements not show d block contraction effect down the group as shown by group 13 . Please explain ........

Answer 1

Explanation:

Heavier element of p-block does show higher oxidation state because of the inert pair effect. 

Heavier element of p-block does show higher oxidation state because of the inert pair effect. The inert pair effect is the tendency of the electrons in the outermost atomic s orbital to remain unionized or unshared in compounds of post-transition metals. 

Heavier element of p-block does show higher oxidation state because of the inert pair effect. The inert pair effect is the tendency of the electrons in the outermost atomic s orbital to remain unionized or unshared in compounds of post-transition metals. The term inert pair effect is often used in relation to the increasing stability of oxidation states that are two less than the group valency for the heavier elements of groups 13, 14, 15 and 16.
