BOHR MODEL TUTORIAL

NITROGEN

• Atomic #.....7
• Mass #......14
• Protons.....7
• Electrons.....7
• Neutrons.....7

• Group.....5
• Period....2
• Valence electrons.....5
• Energy levels....2
• Reactive

First you draw the nucleus and put the protons and neutrons.

Next you draw the energy level/shells for Nitrogen.

You follow the rules 2,8,8 and draw 2 electrons on the first shell.

Add the valence electrons and color them in.
