Answer:
Option A
Explanation:
The choice A accurately specifies and illustrates the orbital diagram of a Nitrogen atom with 7 electrons.
Based on the number of electrons in a Nitrogen atom, there are two energy levels, the s and p sub-levels:
Nitrogen = 2, 5
The first energy level, S will take up two electrons with opposite spin.
The second energy level will have 5 electrons in an S and P orbital.
Configuration 1 is correct because, it satisfies the premise that half and fully filled orbitals are also stable.
