Expert Answer

The general outer configuration of s block elements is ns^1-2

p block = ns²p^1-6

d block= (n-1) d^1-10ns^0-2

f block = (n-2) f^1-14 (n-1) d^0-1,ns²

i) ns² np⁴ for n=3

Ans) In this case the element belongs to third period of the periodic table as n=3. The group number of the element is 16

ii) (n-2)f⁷ (n-1) d¹ ns² for n=6

Ans) In this case the element belongs to the sixth period of the periodic table. The group is lanthanoid. .
