Calcium also shares the same fourth period in the periodic table in which potassium present. The size of the atomic radius decreases from left to right in the period from left to right. Potassium present left to the calcium in the fourth period.
The reason for the decrease in the atomic radius due to the fact though electrons and protons increases but the valence shell remains the same from moving from left to right, therefore, as the net charge increases with the increase in the electrons result in shrinking of the valence shell and resulting in the decrease of the size of the atom.
SS and ss.
