The number of protons, neutrons and electrons in the ion \({ }_{16}^{32} \mathrm{~S}^{2-}\) respectively are
- A \(16,18,16\)
- B \(16,16,18\)
- C \(18,16,16\)
- D \(16,16,16\)
Answer & Solution
Correct Answer
(B) \(16,16,18\)
Step-by-step Solution
Detailed explanation
For \({ }_{16}^{32} \mathrm{~S}^{2-}\),
Number of protons \(=16\)
Number of neutrons \(=32-16=16\)
Number of electrons \(=16+2=18\)
Number of protons \(=16\)
Number of neutrons \(=32-16=16\)
Number of electrons \(=16+2=18\)
