As you move down a group elements have electron shells than those above them

As we move down, a group elements posses more electron shells as compare to the above one.

Explanation:

As we move down in the periodic table than there will be no change in the nuclear charge but now the orbitals are far away, then there is an increase in the orbital radius.

As we know that the elements in the periodic table are arranged in the manner of increasing atomic numbers. All these elements follow a trend of forming an octet, so to achieve noble gas configuration they looses or gain electrons.

And by this completion of octet or in increasing atomic number there will increase in electron shells when we moving down in the periodic table.

Therefore, when we move down, a group elements posses more electron shells as compare to the above one.
