Radius of atoms

WebSep 2, 2024 · Atomic radius is a factor that determines an element's electronegativity or ionization energy. Atoms high in electronegativity have small atomic radii and are near the top right of the periodic... WebFeb 6, 2024 · The ionic radius is half the distance between atomic ions in a crystal lattice. To find the value, ions are treated as if they were hard spheres. The size of an element's ionic radius follows a predictable trend on the periodic table. As you move down a column or group, the ionic radius increases. This is because each row adds a new electron shell.
