Webthe complete transfer of one or more electrons from one atom to another with a bond resulting from the electrostatic attraction between the cation and anion covalent bond a pair of electrons shared between 2 atoms. Form between nonmetals dissociation energy energy required to separate bonded atoms. Indicates bond strength polar covalent bonds WebThe valence electrons in an oxygen atom (box) are attracted to the nucleus by a positive charge nearly double, 1s^2-1box,2s^2-1box,2p^3-3boxes, that of boron. Therefore, the electrons in oxygen are held closer to the nucleus, giving it a smaller radius. Part 2:Electron Configurations of Ions
