Answer:
14 is this value for a molecule of
.
Explanation:
Lewis-dot structure : It shows the bonding between the atoms of a molecule and it also shows the unpaired electrons present in the molecule.
In the Lewis-dot structure the valance electrons are shown by 'dot'.
Number of total outer valence electrons is carbon = 4
Number of total outer valence electrons is hydrogen = 1
Number of total outer valence electrons is chlorine = 7
For total number of outer electrons is
