Q27 / 180 · KCET 2023 · Chemistry
The number of protons, neutrons and electrons in the ion ${ }_{16}^{32} \mathrm{~S}^{2-}$ respectively are
- A$16,18,16$
- Correct answerB$16,16,18$
- C$18,16,16$
- D$16,16,16$
Solution
For ${ }_{16}^{32} \mathrm{~S}^{2-}$,
Number of protons $=16$
Number of neutrons $=32-16=16$
Number of electrons $=16+2=18$
Hence, the correct answer is option: 'B'.
