Answer:
one degenerate orbital is needed
Explanation:
Sulphur has atomic number 16
electronic configuration 1s2 2s2 2p6 3s2 3p4
sulphur has 3d subshell which has similar higher energy level to 3s and 3p because they are in the same principal quantumn shell.
sulphur has 2 bond pairs, 2 lone pairs and 2 unpaired electrons
sulphur obeys octet rule in this compound . the compound undergoes excitation.
