    Solution:

    The valency electrons are far away from the nucleus.

    The electrons present in the inner shells are close to the nucleus, so they do not participate in the chemical bonding.

    Only valency electrons participate in the chemical bonding to attain stability.  Valency electrons are represented by Lewis dot symbols.
