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 answer
    B
    $16,16,18$
  • 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'.
