How do you find the number of PROTONS & ELECTRONS?

• Mass + Atomic Number= Protons

• A=P=E, same as the Mass Number

• A=P=E, same as the Atomic Number

• Mass + Number of Protons = Electrons

What is the formula to solve for the NEUTRON?

• Mass + Atomic Number= Neutrons

• Mass x Atomic Number = Neutrons

• Mass - Atomic Number = Neutrons

• Mass + Number of Protons = Neutron
