Review of Bohr’s Atomic Model
Objectives
To review the placement of electrons within an atom using Bohr’s model. To become familiar with the basic
terminology and concepts concerning the current quantum mechanical model of the atom.
Bohr Model of the Atom
Complete the table to the right by determining the maximum
number of electrons for each energy level.
Bohr Model Diagrams
In the Bohr model diagrams show below, indicate the number
of protons (p) and neutrons (n) in the nucleus of each atom.
Write the number of electrons (e) on each energy level. Not all
energy levels will be used for every element.
