Protons, Neutrons, Electrons... oh my!
How do you determine the number of protons, neutrons, and electrons by just looking at an element square in the periodic table?
EASY! Watch and find out.

Protons & Neutrons in the nucleus
Electrons in the energy levels
Only 2 electrons in the 1st energy level
8 electrons can go in the next few energy levels

Chemical Reactions - Counting Atoms / Determining if equations are balanced
Remember that The Law of Conservation of Mass says that the Mass of the Reactants = the Mass of the Products. We need to count the number of atoms on both sides of an equation to determine if an equation is balanced or not.
