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

(a) Carbon family, [Rn]5f146d107s27p2

(b) Oxygen family, [Rn]5f146d107s27p4

(c) Nitrogen family, [Rn]5f146d107s27p6

(d) Halogen family, [Rn]5f146d107s27p5

Show Answer

Solution:

  1. (a) After 86Rn (Group 18), elements from atomic number 89 to 103 (actinides) are in group 3 114=103+11. Thus, element with atomic number 114 will be in group (3+11) or group 14 (carbon family).

The outer shell configuration of group 14 is ns2=np2.

Hence, only option (a) is correct.
