1 Bohr Model Diagrams Lesson 3.1 Extension

2 F Step 1 9 Determine 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. F 9 18.998 Number of Protons = Number of Electrons = Number of Neutrons = 9 (atomic #) 9 (proton #) 10 (amu – protons)

3 Fluorine F 9 9 10 9 Element Name: _______________________
Chemical Symbol: _______ Atomic Number: _______ Diagram the Bohr atom which contains: 9 10 9 _____ protons _____ neutrons _____ electrons

4 Step 2 Draw a circular nucleus with the correct number of and symbol for both protons and neutrons. The nucleus contains both neutrons and protons. 9p+ 10no

5 Step 3 Draw 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). 9p+ 10no

6 Step 4 Represent electrons as dots in orbits or energy levels/shells.
1st Shell: 2 e- ; 2nd Shell: 8 e- ; 3rd Shell: 18 e- 9p+ 10no
