    The atomic number of an element is equal to the number of protons (this part is correct above) but the atomic mass number is the SUM of the protons and neutrons together. They have (almost) equal weights, normalized to 1. Electrons are not included in the sum because their weight contribution is insignificant.

    okay so what does that mean?

    i means that you add the protons and the neutrons and you get the atomic mass number
