 * 1) What is a covalent bond? A covalent bond is a form of chemical bonding that is characterized by the sharing of pairs of electrons between atoms, and other covalent bonds. In short, the attraction-to-repulsion stability that forms between atoms when they share electrons is known as covalent bonding. Source: []
 * 2) What is an ionic bond? An ionic bond (or electrovalent bond) is a type of chemical bond based on electrostatic forces between two oppositely-charged ions. Source : []
 * 3) List 5 differences between ionic and covalent compounds (Ex. high or low boiling and melting points, sharing or transferring electrons, etc.). Source: []
 * 4) Covalent has a low boiling point and Ionic has a high boiling point.
 * 5) Covalent bonds occur between 2 non metals and Ionic bonds occur between a metal and a non metal.
 * 6) Covalent bonds are liquis or gases and Ionic bonds are solids at room tempurature.
 * 7) Covalent bonds have a definate shape and Ionic bonds do not have a definate shape of their molecules.
 * 8) Ionic bonds are uselly inorganic,and covalent bonds are organic.
 * 9) Find 5 Lewis Structures and copy and paste them on your page. Determine their molecular geometry
