The difference between the atomic number and the mass number is that the atomic number is the number of protons in the nucleus of an atom of that element. The mass number is the total number of protons and neutrons in the atom.
Atomic number = number of protons
Mass number = total number of protons + neutrons
The atomic number of an element is the number of protons in each atom of the element and is the same for all isotopes of an element. Mass number applies only to isotopes and is the sum of the numbers of protons and neutrons in the nucleus of each atom of the isotope.
The atomic number means how many protons are in the element. The mass is the combined number of the protons and neutrons together.
We make atomic number by number of protons in a atom. We make mass number by total of both protons and neutrons.
Atomic mass is the mass of an atom in atomic mass units, and includes protons, neutrons, and electrons; and atomic number is the number of protons in the nucleus of the atom.
Mass number is the total number of protons and number of neutrons.
Atomic mass is the total mass of protons and neutrons
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
Atomic mass is the mass of 1 mole of the element. Atomic number is the number of protons the element has
Calcium-40: The atomic number of calcium is 20 and the number of neutrons is always the difference between the atomic mass and the atomic number.
Atomic mass number is the average atomic mass for that element, which is : All the isotopes' masses known for that element averaged up. Atomic number is the element's "identity", the number of protons the element and all its isotopes have. All the isotopes of a given element will have different number of electrons and neutrons, but the protons of the element never will change.

Nothing, it's the same thing.
Atomic mass is the mass of an atom in atomic mass units, and includes protons, neutrons, and electrons; and atomic number is the number of protons in the nucleus of the atom.
The atomic number is the number of protons the element possesses.
The atomic number of the element is the number of protons or number of electrons in an atom of the element . The atomic weight of the element is the ratio of the mass of the atom to the 1/12th of the mass of the atom of carbon 12.
The atomic number of an element determines the number of protons that are present in that element. The atomic size refers to the distance that the outermost valence electrons are from the nucleus.
All isotopes of an element have the same number of protons in the atomic nucleus, which is its atomic number on the periodic table. All isotopes of an element contain different numbers of neutrons in their atomic nuclei, which causes the isotopes of an element to vary in mass number (protons + neutrons).
