The mass number is the average total of the number of protons and neutrons in the atomic nuclei of all the isotopes of that element on earth. Thus, the average number of neutrons in that element can be found by subtracting the atomic number from the mass number.
atomic number = number of protons
Protons make up the atomic number.
mass
the particle that is represent in the mass number is/ sum equals, protons and neutrons.
Well, this is not exact, but smaller atoms have about the same number (and mass) of neutrons and of protons. Heavier atoms have a larger percentage of their mass in neutrons.Well, this is not exact, but smaller atoms have about the same number (and mass) of neutrons and of protons.

The sum of all Protons and Neutrons.
The mass number is the sum of the protons and neutrons in the atomic nucleus.

The nucleus makes up most of the mass and the other things in the atom make up the rest.
Atoms and elements can vary in many ways. Atoms mainly vary by having different numbers of protons, electrons, and neutrons. The count of protons makes up an elements mass number.
Protons and neutrons are the primary contributors to an atom's mass. Electrons make up an insignificant amount of mass. Atomic mass is determined by adding the number of protons and neutrons in a nucleus.

The molar mass is the sum of the atomic weights of atoms contained in the molecule.
The sum of all Protons and Neutrons.
Atomic number is the number of protons in the nuclei of the atoms of an element. Each element has a unique atomic number. Mass number is the number of protons and neutrons in the nuclei of the atoms of a specific isotope of an element.
