Subatomic particles with a negative charge

• Electrons

• Neutrons

• Protons

• Quarks

Subatomic particles with a positive charge

• neutrons

• atomic mass

• protons

• Nucleus 

• Electrons

This is how you find the number of neutrons in an atom. 

• Subtract the atomic number from the atomic mass

• Subtract the atomic mass from the atomic number 

• Add the atomic mass to the atomic number 

• Divide the atomic mass by the atomic number
