Radius

How can you tell if the radius of an atom has changed?

I don't think atoms of different elements can have the same atomic radius so if the radius of an atom changes, you're probably dealing with a different atom that you initially were.

(NOT ENTIRELY SURE ABOUT THIS, BUT IF I AM WRONG, PLEASE CORRECT ME)

The size of an atom changes depending on the size of the nucleus and how much energy each electron has. An element’s location on the periodic table affects the size, thus the radius changes so if you were to calculate the energy of the electrons you would know that the radius has changed.

When the electron is at a higher energy level, it is further from the nucleus, so it's radius has changed. Because of this, if an electron's energy changes it is likely the radius will change as well.
