<>The maximum no. of electrons present in a shell is given by the formula2n² ( n is shell number).

<>The maximum number of electrons that can be accommodated outermost orbit is 8.

(iii)Electrons are not accommodated in a given shell, unless the inner shells are filled.

The element X with atomic no: 17 is Chlorine.No : of protons = 17No : of electrons = 17

Electronic Configuration = 2 , 8 , 7

The element X with atomic no: 16 is Sulphur.

No : of protons = 16No : of electrons = 16

Electronic Configuration = 2 , 8 , 6
