1. Periodic Table Basics

2. Finding the number of Atomic Particles • # of protons = to the atomic # • # of electrons = to the atomic # • To determine the # of neutrons Subtract the atomics # from the atomic mass

3. Drawing a Bohr Model 1st Energy Level 2 2nd Energy Level 8 Nucleus - Protons - neutrons 3rd Energy Level 18

4. Bohr Model - Hydrogen Hydrogen P1 N0
