Determining the number of Protons, Electrons, and Neutrons
Protons and Electrons
If not electrically charged (will be discussed later), the proton and electron number will be the same as the atom number.
Neutrons
Neutrons can be determined by using this following formula:
Atomic Mass - Atomic Number = Neutron Number
Examples
Proton: 11
Electron: 11
Neutron: 23 - 11 = 12
