Draw a Lewis Dot structure for the valence shell of each element. Rearrange the electrons to pair up electrons from each atom. Draw circles to show the sharing of electrons between each pair of atoms Draw the bond structure using chemical symbols and lines. Use one line for each pair
Thereafter, chemistry became a quantitative experimental science. Lavoisier also contributed greatly to the organization of chemical data, to chemical nomenclature, and to the establishment of the law of conservation of mass in chemical changes.

The atomic number is always written on the bottom left side of the element. The charge (if there is one) is written on the top right side. (see Structure packet!) If no charge is given, assume that atom is neutral (equal protons and electrons). If you are still struggling to remember all the definitions, make...
These atomic properties help describe the macroscopic properties of compounds. For example, smaller covalent compounds that are held together by weaker bonds are frequently soft and malleable. On the other hand, longer-range covalent interactions can be quite strong, making their compounds very durable.
