they describe the same thing. Proton numbers are unique to each element, as are atomic numbers
The number of protons is the atomic number.
Atomic number is the number of protons. Mass number is the total of protons and neutrons.
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 .
atomic number(Z) = no. of protons Detailed: The number of protons in a neutral atom is equal to the number of electrons in the same atom. And the number of electrons in an atom is equal to its atomic number.

The atomic number and number of protons are always the same in a normal element.
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.
Not the atomic mass but the mass number (of course, these values are similar - not identical).The mass number is the sum between the number of protons and the number of neutrons. As a consequence:Number of neutrons for an isotope = Mass number - Number of protonsThe number of protons is equal to the atomic number.
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 of an element represents the number of protons in the nucleus of an atom. It is a unique identifier for each element on the periodic table. The number of protons in an atom determines the element's chemical properties and its place in the periodic table.
Protons are subatomic particles that determine the atomic number of an element. The number of protons in an atom's nucleus is what defines its atomic number; this uniquely identifies each element on the periodic table.
The atomic number represents the number of protons in an atom, while the atomic mass represents the sum of protons and neutrons. Generally, the atomic mass is larger than the atomic number for most elements since it includes both protons and neutrons.
