Bohr Model DiagramsLesson 3.1 Extension
Step 1Determine the number of Particles found in the element.
Number of electrons is equal to the number of protons in a neutral atom. This value is equal to the atomic number.
F9
18.998
Number of Protons =
Number of Electrons =
Number of Neutrons =
9 (atomic #)
9 (proton #)
10 (amu – protons)

Step 2Draw a circular nucleus with the correct number
of and symbol for both protons and neutrons.
The nucleus contains both neutrons and protons.

Step 3Draw the correct number of electron shells
(equal to the period of the element on the periodic table).
Therefore, fluorine is found in period #2 (2 shells).

Step 4Represent electrons as dots in orbits or energy
levels/shells.

Bohr Model DiagramsYou are responsible for doing 8 Bohr Models.
You may choose from the first 18 elements.
You may not do any that your partner are doing.
Make sure that it is very neat.
