GPT 3.5
The sum of protons and neutrons in the nucleus of an atom is equal to the atomic mass number. The atomic mass number is denoted by the letter "A" and is specific to each atom. It represents the total number of protons and neutrons in the nucleus.

For example, if an atom has 7 protons (atomic number) and 8 neutrons, the sum of protons and neutrons (A) is 7 + 8 = 15. Therefore, the atomic mass number is 15.
