Q.

The element Z = 114 has been discovered recently. It will belong to which of the following family/group and electronic configuration             [2017]
 

1 Carbon family, [Rn] 5f146d107s27p2  
2 Oxygen family, [Rn] 5f146d107s27p4  
3 Nitrogen family, [Rn] 5f146d107s27p6  
4 Halogen family, [Rn] 5f146d107s27p5  

Ans.
