Bohr Model - Home - Polk School District

Do and Answer Draw a Bohr Model for Oxygen Hydrogen (twice) Using the drawing try to draw a Water Molecule. Define: atom, compound, molecule

Bohr Model What is a Bohr Model? Shows all the protons, neutrons, and electrons contained within an atom.

Protons and neutrons are drawn in the Nucleus. Electrons are drawn on ENERGY LEVELS or SHELLS or ELECTRON CLOUDS (the rings found around the nucleus).

Energy Levels Energy levels can only hold a certain amount of electrons. Energy Level Maximum Number of Electrons

1 2 3 4 5

2 electrons 8 electrons 18 electrons 32 electrons 50 electrons

Bohr Model Quiz Energy Level Maximum Number of Electrons

1 2 3 2 electrons 8 electrons

18 electrons Question 1: Flourine Protons = 9 Electrons = 9 Neutrons = 5

Question 2: Magnesium Protons = 12 Electrons = 12 Neutrons = 12
