Ionic, Covalent and Metallic bonds are the three divisions of bonds that occur. The ionic bond is the complete transference of electrons from one atom to another. In the process of either losing or gaining negatively charged electrons, the reacting atoms form ions. One atom will be nonmetal and one will be metal;therefore, one will have a low electronegativity value while the other has high. Ionic bonds have very high melting points, they dissolve easily in water, well defined crystals and can conduct electricity. Examples include: NaCl, CaCO3. Covalent Bonds happen when a pair of electrons are shared between atoms in a molecule. A metal plus a nonmetal can form a Covalent bond. Characteristics in a covalent bond are: definite shape, low boiling point, and a low polarity. Some examples are HCl H2,and SO2. Metallic bonds are the electromagnetic interaction between delocalized electrons, and the metallic nuclei within metals. Metallic bonds have many physical properties of metals such as a high electrical conductivity, luster and malleability. Some examples are gold, silver and mercurous ion.
