Given the outer electronic configuration of s,p,d and f-block elements.

Explanation

`{:("Block",,"outer electronic configuration"),((a) "s-block",rarr,ns^(1-2)),((b) "p-block",rarr,ns^(2)np^(1-6)),((c )"d-block",rarr,ns^(1-2) (n-1)d^(1-10)),((d) "f-block" ,rarr,ns^(2)(n-1)d^(0 or 1) (n-2) f^(1-14)):}`
