Question

The number of paired and unpaired electrons in the valence shell of sulphur is:

• A. 2, 2
• B. 4, 2
• C. 2, 4
• D. 0, 6

Answer 1

The correct option is B 4, 2

The electronic configuration of sulphur is: $\left[Ne\right]3s^{2}3p^4$
According to Hund’s rule, the pairing of electrons in the degenerate (equal energy) orbitals is not done before each of these orbitals are singly occupied.

It has 4 paired and 2 unpaired electrons.
