Ionic bonds versus Covalent bonds. In ionic bonds, electron pairs are shared between atoms. In covalent bonds, atoms are electrostatically attracted towards each other. The atomic radius is a term used to describe the size of the atom. The ionization energy is the energy required to completely remove an electron from a gaseous atom or ion.
