What is the formula to get the mass number of an element?
Mass Number = # of Protons + # of Neutrons
What is the formula to get the number of protons of an element while looking at the periodic table?
Atomic Number = # of Protons
What is the formula to get the number of neutrons of an element?
# of Neutrons = Mass # - # of Protons
What is the formula to get the number of protons of an element using the formula to get the mass number?
