Write the general electronic configuration of sp-d-, and f-block elements?

Explanation

(i) s-block elements: `ns^(1-2)` where n=2-7.
(ii) p-block elements, `ns^(2)np^(1-6)` where n-2-6
(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^0-1)ns^(2)` where n=6-7.
