WebMar 16, 2024 · Atomic size is the distance from the nucleus to the valence shell. Ionization energy is the energy required to remove the most loosely held electron from a gaseous atom or ion. Ionization energy increases across a period and decreases down the family. So as the Atomic size increase so does Ionization Energy. WebFeb 7, 2024 · An atomic radius is one-half the distance between the nuclei of two atoms. Atomic radii are measured in picometers (one picometer is equal to one trillionth of a meter). Hydrogen (H) has the smallest average atomic radius at about 25 pm, while caesium (Cs) has the largest average radius at about 260 pm. What Are the Atomic Radius Trends?
