Element 'P' has electronic configuration 2,8,8,1. The number of chlorine atoms present in the chloride of 'P' is:

1

Reason — P has 1 electron in its outermost shell. Since each chlorine atom can accept one electron, the chloride of P will have one chlorine atom for one electron lost by P. Therefore, the number of chlorine atoms in the chloride of 'P' will be 1.
