Answer: -
The number of valence electrons in sulfur = 6
Explanation: -
Atomic number of sulfur = 16
The number of electrons = 16
The electronic configuration of sulfur = [Ne] 3s²3p⁴
The number of valence electrons in sulfur = Number of electrons present in 3s + number of electrons present in 3p
= 2 + 4 = 6
