  1. Hello Minions!!! How to Draw Bohr Diagrams

  2. Bohr Diagrams • Draw a nucleus with the element symbol inside. • Carbon is in the 2nd period, so it has two energy levels, or shells. • Draw the shells around the nucleus. C

  3. Bohr Diagrams • Find your element on the periodic table. • Determine the number of electrons – it is the same as the atomic number. • This is how many electrons you will draw.

  4. Bohr Diagrams • Find out which period (row) your element is in. • Elements in the 1st period have one energy level. • Elements in the 2nd period have two energy levels, and so on. www.chem4kids.com

  5. Bohr Diagrams • Add the electrons. • Carbon has 6 electrons. • The first shell can only hold 2 electrons. C

  6. Bohr Diagrams • Since you have 2 electrons already drawn, you need to add 4 more. • These go in the 2nd shell. • Add one at a time -starting on the right side and going counter clock-wise. C

  7. Bohr Diagrams • Check your work. • You should have 6 total electrons for Carbon. • Only two electrons can fit in the 1st shell. • The 2nd shell can hold up to 8 electrons. • The 3rd shell can hold 18, but the elements in the first few periods only use 8 electrons. C

  8. Bohr Diagrams Try the following elements on your own: • H • He • O • Al • Ne • K C

  9. Bohr Diagrams Try the following elements on your own: • H – 1 electron • He • O • Al • Ne • K H

  10. Bohr Diagrams Try the following elements on your own: • H • He - 2 electrons • O • Al • Ne • K He

  11. Bohr Diagrams Try the following elements on your own: • H • He • O - 8 electrons • Al • Ne • K O

  12. Bohr Diagrams Try the following elements on your own: • H • He • O • Al - 13 electrons • Ne • K Al

  13. Bohr Diagrams Try the following elements on your own: • H • He • O • Al • Ne - 10 electrons • K Ne

  14. Bohr Diagrams Try the following elements on your own: • H • He • O • Al • Ne • K - 19 electrons K
