Electronegativity.

A chemical bond is the energy that holds two atoms together in a compound. This energy can be further broken down into ionic bonding and covalent bonding. An ionic bond is a chemical bond characterized by attraction between ions of opposite charge. The formation of an ionic bond involves a complete transfer of electrons between atoms, and can be predicted when one atom has a much higher electronegativity than the other. A covalent bond is a very strong chemical bond formed by the sharing of electrons. Multiple covalent bonds can be formed when multiple pairs of electrons are shared between…
