Ionic Radius Trends in the Periodic Table

WebJun 4, 2024 · Ionic radius decreases moving from left to right across a row or period. More protons are added, but the outer valence shell remains the same, so the positively charged nucleus draws in the electrons more tightly. While the atomic radius follows a similar trend, ions may be larger or smaller than neutral atoms. WebApr 9, 2024 · The periodic trend of atomic radius across a period – As we move from left to right in a period, atomic radius gradually decreases. Reason – As we move left to right in a period the atomic number of the elements increases so nuclear charge increases while the number of shells in elements remains the same. Example –.
