Question

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

• A. Halogen family, $\left[Rn\right]5F^{14},6d^{10},7s^2,7p^5$
• B. Carbon family, $\left[Rn\right]5F^{14},6d^{10},7s^2,7p^2$
• C. Oxygen family,$\left[Rn\right]5F^{14},6d^{10},7s^2,7p^4$
• D. Nitrogen family, $\left[Rn\right]5F^{14},6d^{10},7s^2,7p^6$

Answer 1

The correct option is B

Carbon family, $\left[Rn\right]5F^{14},6d^{10},7s^2,7p^2$

The element with atomic number, Z = 114 is flerovium (FI). It is a heavy artificial chemical element. In the periodic table of the elements, it is a transition element in the p - block. It is a member of the 7th period and is the heaviest known member of the carbon family.
Electronic configuration for Z = 114 is
$[Rn{]}_{86}5F^{14},6d^{10},7s^2,7p^2$
