  1. e P N e e II. Bohr Model (Don’t copy in flipbook) a. Developed by Neils Bohr b.Found that electrons exist in definite orbits around the nucleus c. Electrons have different amounts of energy (called ENERGY LEVELS)

  2. II. The BOHR Model d. Electrons are placed in Energy Levels i. Energy Level 1 holds up to 2 electrons ii. Energy Level 2 holds up to 8 electrons iii. Energy Level 3 holds up to 8 electrons iv. Energy Levels 4, 5, 6, & 7 hold up to 32 electrons ***You MUST fill up the previous level before filling up the next levels***

  3. III. The Steps to Drawing a Bohr Model Steps to drawing a Bohr Model - THERE IS A PARTICULAR ORDER IN WHICH YOU FILL ELECTRONS 1. Calculate the # of protons, neutrons, & electrons in the atom (APEMAN) 2. Draw a small circle to represent the nucleus of the atom 3. fill in the # of protons & neutrons in the nucleus 3P 3N EX.: Lithium-6

  4. III. Steps to drawing a Bohr Model, cont’d. 4. Draw a larger circle around the nucleus to represent the first energy level 5. fill in the electrons in the first energy level 6. Draw additional energy levels, if needed, and fill in the remaining electrons EX: Lithium-6 e

  5. Bohr Model 1 Hydrogen-1 2 Helium-4 3 Lithium- 7 4 Beryllium-9 5 Boron-11 6 Carbon-12 7 Nitrogen-14 8 Oxygen-16 9 Fluorine-19 10 Neon-20 11 Sodium-23 12 Magnesium-24 13 Aluminum-27 14 Silicon-28 15 Phosphorus-31 16 Sulfur- 32 17 Chlorine-35 18 Argon-40 19 Potassium-39 20 Calcium-40

  6. The BOHR Model • Alkali Metals: • Sodium • A = 11 • P = 11 • E = 11 • M = 23 • A = 11 • N = 12

  7. The BOHR Model • Halogens: • Fluorine • A = 9 • P = 9 • E = 9 • M = 19 • A = 9 • N = 10
