The rules for writing of the distribution of electrons in various shells for the first eighteen elements are given below. The valency becomes zero for an atom when the outer bounds have eight electrons or no electrons to lose. However, it was later found that the positively charged particles reside at the centre of the atom called the nucleus, and the electrons revolve around the nucleus.
