Web3 jul. 2024 · Ionization decreases moving top to bottom down an element group (column). This is because the principal quantum number of the outermost electron increases moving down a group. There are more protons in atoms moving down a group (greater positive charge), yet the effect is to pull in the electron shells, making them smaller and … Web16 jul. 2024 · Ion Examples With Positive & Negative Charges.

3.3: Predicting Charges of Ions - Chemistry LibreTexts
WebIonic radii follow the same vertical trend as atomic radii; that is, for ions with the same charge, the ionic radius increases going down a column. The reason is the same as for atomic radii: shielding by filled inner shells produces little change in the effective nuclear charge felt by the outermost electrons.
