Solution: In keeping with Kossel and Lewis, atoms Blend collectively in order to comprehensive their respective octets so as to accumulate the steady inert gasoline configuration.
Lack of an electron from an atom ends in the formation of the cation. A cation is smaller sized than its dad or mum atom because it has fomer electrons even though its nuclear charge remains a similar. One example is, The atomic radius of sodium (Na) is 186 pm and atomic radius of sodium ion (Na+) = ninety five pm.
