The atomic number represents the number of protons in the nucleus. It determines what element you're talking about. Numbered from 1 to over 100.
The mass number represents the total of protons AND neutrons in the nucleus.
It is close to (not the same as) the Atomic Mass. Isotopes can have different mass numbers but belong to the same element (same atomic number).
The number of neutrons (not having a special 'name') varies from 0 to over 150.

What is the difference between the atomic number mass number and atomic mass?
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.
What is Relation between atomic and mass numbers?
mass number=atomic number+no. of neutrons
What are the differences between atomic number and atomic mass?
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.
What is the difference between the atomic number and average atomic mass?
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.
What best describes the number of neutrons in an atom?
It is equal to the difference between atomic number and Atomic Mass number. A+
What is the difference between the atomic number an its atomic mass?
Atomic number is the amount of electrons. Atomic mass is the amount of protons and neutrons.
What is the difference between atomic number and atomic mass weight?
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.
What are some differences between atomic mass and atomic number?
Atomic mass is how much it weighs, the atomic number is how many protons/electrons it has
Difference between atomic and mass number?
Atomic number shows the number of protons in an element and the mass number shows the number of protons+neutrons In an electrically neutral atom, atomic number is also the number of electrons .
What is the diffrince between mass number and atomic number?
Atomic number is the number of protons. Mass number is the total of protons and neutrons.
What is difference between atomic weight and atomic mass?
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.
What is the difference between atomic mass and atomic weight?
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.
