The attraction between the nucleus and electrons decreases tends to occur in groups that results in an increase in atomic radius.
Magnesium atoms have atomic radii that are lower than those of sodium atoms. The magnesium atom's smaller radius is mainly due to the fact that it has two more electrons in its outermost energy level than the sodium atom does.The attractive interactions between the nucleus and the additional electrons in the magnesium atom make them weaker, which leads to a reduced atomic radius. An element's atomic radius serves as a gauge for the size of its atoms.
