1) A covalent bond is formed between the atoms of non-metals, and an ionic bond between the atoms of metals and non-metals. 2) In an ionic bond, an electronegative element (this is usually a nonmetal) completely attracts a common electron pair, and in a covalent bond, it only slightly shifts to a more electronegative one.
