Question

Assign the position of the element having our electronic configuration (i) ns² np⁴ for n = 3, (ii) (n - 1) d² ns² for n = 4 and (iii) (n - 2) f⁷ (n - 1) n¹ ns² for n = 6 in the periodic table.

Answer 1

(i) The element is present in third period (n = 3) and belongs to group 16 (10 + 2 + 4 = 16).

(ii) The element is present in fourth period (n = 4) and belongs to group 4 (2 + 2 = 4).

(iii) The elements present in sixth period (n = 6) and belongs to group 3.
