Btw 10th Studies gonna start!!!

.

And what about you??

Explanation:

This is because electrons are added in the same valence shell. Consequently a proton is also increased in the nucleus of the atom. ... In period as we move left to right the atomic radius decreases. So in a period the alkali metal will have the highest Atomic Radius and the Noble gas will have the lowest Atomic Radius.
