Write the general outer electronic configuration of `s-`,`p-`,`d-` and `f-block` elements.

Explanation

(i) s- block element `: ns^(1-2) ` where n=2-7 (ii) p-Block elements `: ns^(2) np^(1-6)` where n= 2-7
(iii) d- Block elements `: (n-1) d^(1-10) ns^(0-2) ` where n=4-7
(iv) f- Block elements `: (n-2) f^(0-14) ` (n-1) `d^(0-2) ns^(2)` where n= 6-7
