(a) Carbon family, [Rn] 5f¹⁴ 6d¹⁰ 7s² 7p²

(b) Oxygen family, [Rn] 5f¹⁴ 6d¹⁰ 7s² 7p⁴

(c) Nitrogen family, [Rn] 5f¹⁴ 6d¹⁰ 7s² 7p⁶

(d) Halogen family, [Rn] 5f¹⁴ 6d¹⁰ 7s² 7p⁵

Answer 1

Ans : (a) Carbon family, [Rn] 5f¹⁴ 6d¹⁰ 7s² 7p²

Explanation :

The electronic configuration of the element with Z = 114 (Flerovium) is [Rn] 5f¹⁴ 6d¹⁰ 7s² 7p².

It belongs to 7th period and 14th group.

Hence, it belongs to carbon family which has the same outer electronic configuration.
