Covalent and ionic atomic sizes: covalent radius, which is defined as one-half the distance between the nuclei of two identical atoms when they are joined by a covalent bond (this measurement is possible because atoms within molecules still retain much of their atomic identity). Ionic radius is the measure used to describe the size of an ion. Ionization energy: Energy required to remove an electron from a gaseous atom or ion. Electron affinity: Electron affinity (the energy associated with forming
