Name Bohr Model Diagrams Period Date Energy Level 1 can hold: Energy Level 2 can hold: Energy Level 3 can hold: Energy Level 4 can hold: electrons electrons electrons electrons Use the information provided for each element to draw Bohr Model diagrams. Rather than drawing individual protons and neutrons, you may simply label how many of each there are in the nucleus (e.g. He: 2p, 2n). Then, write the number of electrons on the appropriate energy levels (keep in mind the maximum number of electrons allowed on each level). These are neutral atoms. 1.
