Atomic mass is a number that represents the amount of matter in an atom or isotope of a certain element, specifically the number of protons and neutrons. Atomic mass is calculated as an average mass of the different isotopes of each element. The unit for atomic mass is ''amu,'' which ...

So the atomic mass formula is: atomic mass (u) ≈ number of protons + number of neutrons Or A=Z+NA=Z+N where: AA— Mass number (total number of protons and neutrons); ZZ— Number of protons in the atom; and NN— Number of neutrons in the atom. Note that the mass of an atom...
