Which of the following is isoelectronic with carbon?

Options

A. `N^(+)`
B. `Al^(3+)`
C. `O^(2-)`
D. `N^(+)`

Answer

D

Explanation

Number of electrons in C = 6
Number of electrons in `Al^(3+) = 13 - 3 = 10`
Number of electrons in `O^(2-) = 8 + 2 = 10`
Number of electrons in `N^(+) = 7 - 1 = 6`
`:. N^(+)` iso - electronic with C.
