This is a modification of Coulumb's law. B. Covalent bonding is where the atoms share the electrons. Polar covalent bonding is where there is an unequal sharing of electrons. There is a partial charge on each atom of this polar covalent bond. The ability of an atom to attract shared electrons to itself.
Electronegativity increases from left to right and bottom to top on the periodic table.
Electron Configuration and Sizes A. Bonding involves atoms attaining the number of valence electrons of the nearest noble gas. To predict the formula of the ionic compound, simply balance the compound so that it is neutral. The ration of protons to electrons greatly influences the size of the ions. The greater number of protons the smaller the ion will be. The strength of an ionic bond is indicated by the lattice energy or the change in energy that takes place when separated gaseous ions are packed together to form an ionic solid.
