Atomic mass and number

Atomic mass is the number at the top of the symbol and tells us the amount of neutrons and protons.i.e. sodium as and atomic mass of 23- 11 protons and 12 neutrons

The atomic number is the number of electrons and number of protons.i.e. sodium has an atomic number of 11-11 protons and 11 electrons
