# Protons = # electrons, net charge of 0
1--Electromagnetic Forces
Keep the Electrons in Orbit
2--Strong Nuclear Forces
Keep Protons from Repelling
3--Weak Nuclear Forces
Keep the nucleus stable
4--Gravitational Forces
Exist between all objects but too small in atoms to have any large effect
How do we know how many Protons, Neutrons, and Electrons are in an atom?
