Atomic number defines as how many nmbr of electrons and protons d atom contain.
No. of electron=No. of protons=Atomic Nmbr.
Atomic Mass defines d mass of total protons and neutrons(mass of nucleus) of an atom.

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 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.
