Q12 / 60 · KVPY 2015 (SA) · Chemistry

The element which readily forms an ionic bond has the electronic configuration.

  • A
    $1 s^{2} 2 s^{2} 2 p^{3}$
  • B
    $1 s^{2} 2 s^{2} 2 p^{1}$
  • C
    $1 s^{2} 2 s^{2} 2 p^{2}$
  • Correct answer
    D
    $1 s^{2} 2 s^{2} 2 p^{6} 3 s^{1}$

Solution

Metals form ionic bond as they have low ionization energies. $1 \mathrm{~s}^{2} 2 \mathrm{~s}^{2} 2 \mathrm{p}^{6} 3 \mathrm{~s}^{1}:$ Sodium metal

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