 * 1) What is a covalent bond?
 * A chemical bond formed by the sharing of one or more electrons, especially pairs of electrons, between atoms.


 * 1) What is an ionic bond?


 * A chemical bond between two ions with opposite charges, characteristic of salts. Also called //electrovalent bond//


 * 1) List 5 differences between ionic and covalent compounds (Ex. high or low boiling and melting points, sharing or transferring electrons, etc.).
 * 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. 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.


 * 1) Find 5 Lewis Structures and copy and paste them on your page. Determine their molecular geometry.

 * CO: Name- Carbon Oxide
 * this is a covalent compound because the first element isnt a metal. it is covalent so there are no charges. the only thing that happens is oxygen changes to oxide because you have to add the -ide ending.
 * 1) H3 PO4: Name- Phosphoric Acid
 * this is an acid because hydrogen is the first element. because hydrogen is bonded to phosphate, i used the naming rule number 3 for -ate,which is that it turns to -ic.
 * 1) Nitrous Acid: Formula- H3 N3
