Which of the following properties is incorrect for the ion ³¹S²⁻?
- Number of electrons 14
- Number of neutrons 15
- Number of nucleons 31
- Nuclear charge +16
📝 Batafsil tushuntirish
Sulfur has an atomic number of 16, so p = 16 and nuclear charge is +16.Neutrons = Mass number - Protons = 31 - 16 = 15.
Nucleons = Mass number = 31.
Electrons for S²⁻ = p + 2 = 16 + 2 = 18.
Option A states 14, which is incorrect.
