Explanation:

It is known that when we move from left to right along a period then there occurs increase in number of electrons due to increase in atomic mass.

So, addition of electrons in same sub shell increases which leads to increase in the size of atomic orbital.

Hence, we can conclude that periods on the periodic table represent elements with the same number of electron orbits with increasing atomic size.
