MCQ
The electronic configuration of an element with atomic number $7$ i.e. nitrogen atom is
- A$1{s^2},2{s^1},2p_x^3$
- B$1{s^2},2{s^2}2p_x^22p_y^1$
- ✓$1{s^2},2{s^2}2p_x^12p_y^12p_z^1$
- D$1{s^2},2{s^2}2p_x^12p_y^2$
✓
Answer
Correct option: C.
$1{s^2},2{s^2}2p_x^12p_y^12p_z^1$
c
(c) $_7N = 1{s^2},2{s^2}2p_x^1,\,2p_y^1,\,2p_z^1$. Hund’s rule states that pairing of electrons in the orbitals of a subshell (orbitals of equal energy) starts when each of them is singly filled.
