SUMMARY
Atomic radii decrease from left to right across the periodic table due to the increase in nuclear charge as the number of protons increases. This increase in protons results in a stronger attractive force on the electrons, causing them to be pulled closer to the nucleus. Although the number of electrons also increases, their repulsive forces do not counterbalance the stronger pull from the protons, leading to a reduction in atomic radius.
