Calculate the number of protons, neutrons and electrons in \({ }_{16}^{32} \mathrm{~S}^{2-}\).
- A \(14,18,16\)
- B \(16,16,14\)
- C \(18,16,14\)
- D \(16,16,18\)
Answer & Solution
Correct Answer
(D) \(16,16,18\)
Step-by-step Solution
Detailed explanation
An element can be represented as \({ }_Z^A X\). where, \(X=\) symbol of element \(Z=\) atomic number or number of protons \(A=\) mass number \(=\) sum of number of protons and neutrons Therefore, for \({ }_{16}^{32} \mathrm{~S}^{-2}\), number of protons \(=16\), number of…
