Solution

The correct option is D

8


  • Valence shell: The outermost shell of an atom is known as valence shell.
  • The electrons present in the valence shell (outermost shell) are known as valence electrons.
  • For example, if the electronic configuration of a sodium atom is 2,8,1, then its outermost shell has 1 valence electron.
  • The number of valence electrons can vary from 1 to 8 in different elements.
  • Thus, the maximum number of electrons in the valence shell can be 8.

Hence, option (D) is the correct answer.
