Ionic and Covalent Chemical Bond

• Ionic Bonds:

Ionic bonds are bonds that are formed between two atoms, usually a metal and a non-metal through loosing or gaining an electron. The metal looses one or more electrons and the non-metal gains one or more electrons. What this does is it makes "ions" ions are atoms that are charged because they gained or lost an electron. These ions have a positive (for the metal) or negative (for the non-metal) charge and because of that they attract to each other and form the ionic bond.
      
             A molecule or compound is made when two or more atoms form a chemical bond, linking them together. The two types of bonds are ionic bonds and covalent bonds. In an ionic bond, the atoms are bound together by the attraction between oppositely-charged ions. For example, sodium and chloride form an ionic bond, to make NaCl, or table salt.

• Covalent Bonds:

              Covalent bonds are usually between two non-metals. Covalent bonds involve atoms that SHARE electrons, these atoms do not loose or gain electrons but instead will share them to gain a full outer energy level. By sharing electrons each atom pulls on them and the atoms form a bond through the electron sharing known as the covalent bond.

                  In a covalent bond, the atoms are bound by shared electrons. If the electron is shared equally between the atoms forming a covalent bond, then the bond is said to be nonpolar. Usually, an electron is more attracted to one atom than to another, forming a polar covalent bond. For example, the atoms in water, H₂O, are held together by polar covalent bonds. Do you understand?
