The element Z=114 has been discovered recently. It will belong to which of the fallowing family/group and electronic configuration-

A

carbon family, `[Rn]5f^(14)6d^(10)7s^(2)7p^(2)`

B

oxygen family, `[Rn]5f^(14)6d^(10)7s^(2)7p^(4)`

C

nitrogen family, `[Rn]5f^(14)6d^(10)7s^(2)7p^(6)`

D

`halogen family, `[Rn]5f^(14)6d^(10)7s^(2)7p^(5)`

Text Solution

Verified by Experts

The correct Answer is:
A
The electronic configuration of the element having atomic mass 114 is `[Rn]5f^(14)6d^(10)7s^(2)7p^(2)`. The outer electronic conifiguration of the element is same as that of carbon. So the elemennt should belong to the carbon family.
