In the formation of the N2 molecule a bond is formed between 2 N atoms. In this
                              bond there are three pairs of bonding electrons. Thus, the N2 molecule has one

                              triple bond which is denoted by a triple line.

                                Why can't water and oil mix? Have you ever heard the term "like dissolves
                          like". The term is an expression that occurs in the dissolving process. This means

                          that substances that are polar will only dissolve in polar solvents and vice versa.
                          1.  Covalent Polar Bond

                                   The polarity of a covalent bond is determined by the electronegativity of

                              an element. Polar covalent compounds usually occur between atoms of elements
                              with large electronegativity differences, have an asymmetrical molecular shape,

                              and have a dipole moment. The covalent bond that occurs between two different
                              atoms is called a polar covalent bond.

                                   A polar covalent bond occurs when the shared electron pair is polar to one

                              of  the  atoms.  The  atom  is  polar  because  there  is  a  large  difference  in
                              electronegativity between the bonded atoms. When the electrons are polarized,

                              a dipole is formed. There is one side that is positive while the other side is
                              negative. In a polar covalent bond, the electron pairs tend to approach the atom
