Q9 / 170 · Manipal (MET) 2016 · Chemistry

The Pauli exclusion principle applies to the following option.

  • A
    H
  • B
    $\mathrm{H}^{+}$
  • Correct answer
    C
    $\mathrm{H}^{-}$
  • D
    $\mathrm{He}^{+}$

Solution

Since, $\mathrm{He}^{+}$and H have one electron each, while $\mathrm{H}^{+}$ has no electron, hence Pauli exclusion principle does not apply to them. However, $\mathrm{H}^{-}$has two electrons, hence this principle applies on it.

Hence, the correct answer is option: 'C'.
