 How do you find the number of protons, neutrons, and electrons in an atom? 


To calculate the number of protons, neutrons, and electrons in an atom, find the atomic number  for protons and electrons, and the mass number for neutrons. Protons equal the atomic number, which also equals the number of electrons in a neutral atom. Neutrons are calculated by subtracting the atomic number from the mass number, etc.
