Presentation Transcript

  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

  5. Helium P P2 N N1

  6. Boron P N

  7. How would you rate your Understanding of this? 4I know the content enough to teach it to someone 3I can do it on my own and explain the concepts 2 I know all the terms without help 1 I know almost all the terms. I can get it with help. 0 With help I don’t understand

  8. Gallium P N

  9. Valence Electrons • Electrons found in the outer most energy level

  10. Lewis Dot Structure
