  1. Bohr Models Niels Bohr Practice drawing models of atoms

  2. How to use this document • Draw a Bohr model. (draw on markerboard or paper) • When you finish drawing, go to the next slide to see a correct drawing. • Compare your drawing to the “answer.” Go back to your packet if you make mistakes – reread your notes and/or worksheets we’ve done to figure out what went wrong. • Try again with the next slide.

  3. Draw a Bohr model for…Helium (He)

  4. Don’t go to the next slide until you are finished drawing your model!

  5. Helium e e 2 P 2 N

  6. Draw a Bohr model for…element with atomic mass of 9

  7. WAIT! DON’T PEEK!Unless, of course, you’re finished…

  8. Beryllium has an atomic mass of 9 e e e 4 P 5 N e

  9. Draw a Bohr model for…element that has 9 protons Wait to move on until you are finished drawing! 

  10. Fluorine has 9 protons (we know the protons because of the atomic number) e e e e 9 P 10 N e e e e e

  11. Draw a Bohr model for…element with the symbol Mg Wait to move on until you are finished drawing! 

  12. Magnesium has the symbol Mg(be careful not to confuse it with Mn – Manganese or Minnesota) e e e e e e e 12 P 12 N e e e e e

  13. Draw a Bohr model for…element with atomic mass of 27 Wait to move on until you are finished drawing! 

  14. Aluminum has an atomic mass of 27 e e e e e e e 13 P 14 N e e e e e e

  15. How did you do? • Write down your results in your packet. • If you drew your models correctly, congratulations! • If you made several mistakes, go back over your notes, ask questions, check ediscio, then try these again.
