                          Based on the bonds formed:
                              •  Single Bond
                              •  Double Bond

                              •  Triple Bond
                          Based on the Polarization:
                              •  Covalent Polar
                              •  Covalent Non-Polar

                          Based on The Electron Source:
                              •  Coordinate Covalent
                                 Bond






                   B.  Brief Description
                              A chemical bond can be defined as the force that causes a group of the same or

                      different atoms to unite with the same behavior, have a lower energy level and are more

                      stable than the atoms themselves. Maximum stability is achieved if the bonded atoms
                      have  the  same  electron  configuration  as  the  noble  gas  elements  (duplet  or  octet

                      structure). There are different kinds of bonds depending on how the atoms are joined
                      together (ionic, covalent, metallic, hydrogen, and Van der Waals bonds).
