How does atomic radius decrease

Weband the atomic radius decreases. You might expect the atomic radius to increase because the number of electrons in each atom increases going across period 3. However, this does not happen: the number of protons also increases and there is relatively little extra shielding from electrons in the same shell. WebAug 14, 2024 · In the periodic table, atomic radii decrease from left to right across a row and increase from top to bottom down a column. Because of these two trends, the largest atoms are found in the lower left corner of the periodic table, and the smallest are found in the upper right corner (Figure ).
