How does ionic radius change across a period

WebMar 25, 2024 · Ionic radii decreases across a period. This is due to the fact that metal cations lose electrons, causing the overall radius of an ion to decrease. Non-metal cations gain electrons, causing the overall radius of an ion to decrease, but this happens in reverse (compare fluorine to oxygen and nitrogen, which one gains the most electrons). WebNov 6, 2024 · Both atomic and ionic radius follow the same trend on the periodic table. Generally, radius decreases moving across a period (row) and increases moving down a group (column). Atomic Radius The atomic radius is the distance from the atomic nucleus to the outermost stable electron of a neutral atom.

WebNotice that, within the series of positive ions, and the series of negative ions, that the ionic radii fall as you go across the period. We need to look at the positive and negative ions separately. The positive ions In each case, the ions have exactly the same electronic structure - they are said to be isoelectronic. 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.
