The electronic configuration of an atom of Nitrogen is 1s\(^2\) 2s\(^2\) 2p\(^1_x\) 2p\(^1_y\) 2p\(^1_z\) because the atom is
- in an excited state
- undergoing energy changes
- unstable and ready to combine with another
-
simply obeying rules governing electron configuration
The correct answer is: D
Explanation
The rules governing electron configuration are the Aufbau principle, Pauli's exclusion principle, and Hund's rule:
- Aufbau principle: Electrons fill the lowest energy orbitals first.
- Pauli's exclusion principle: No two electrons can have the same spin in one orbital. Each orbital can hold a maximum of two electrons with opposite spins.
- Hund's rule: Electrons fill empty orbitals singly before pairing up in the same sub-levels.
