Question

An element attains the stable configurations, when _______ electrons are there in the valence shell.

  1. 6
  2. 8
  3. 4
  4. 2

hintHint:

Electronic configuration of atoms follows the octet rule.

The correct answer is: 8


    • Atoms have different shells of electrons, each shell contains a set number of maximum electrons.
    • The electronic configuration is done in accordance with the octet rule which states a max number of 8 electrons can be in one shell after the first shell.
    • Atoms are most stable when their outer valence shell is full with eight electrons.
