WebNov 2, 2024 · Atomic Radius Simply put, the atomic radius is half of the diameter of the atom, which is a result of the number of protons, neutrons, and electrons that compose the atom. Generally, it would... The atomic radius of a chemical element is the distance from the center of the nucleus to the outermost shell of an electron. Since the boundary is not a well-defined physical entity, there are various non-equivalent definitions of atomic radius. Depending on the definition, the term may apply only to isolated atoms, or also to atoms in condensed matter, covalently bound in molecules, or in ionized and excited states; and its value may be obtained through experimental measuremen…
