How do you find the number of protons
The atomic number
How do you find the number of electrons
It’s the same as the number of protons which is the atomic number
How do you find the number of neutrons
It’s the mass number - the number of protons (atomic number)
What particles are in the nucleus

What is protons charge and mass
It’s charge is +1 and it’s mass is 1
What is neutrons charge and mass
Charge is 0 and mass is 1
What is an electrons charge and mass
Charge is -1 and mass is 1/836 or 0
