Each isotope of an element has an Atomic Mass. The average of all the atomic masses of an element's isotopes gives an elements atomic weight. For this reason, atomic weights are decimal numbers.
The relationship between the mass number of an element and the isotopes of that element is that form each isotope, there will be a different mass number. A given element is identified by the number of protons in its nucleus. Only that. And it will have some neutrons (hydrogen in the form of 1H being the exception). The number of protons plus the number of neutrons equals the atomic mass. Every element has an isotope (or two or more), and each isotope of an element will have a different number of neutrons in it (all having the same number of protons - they're all the same element). This translates into a different (a unique) mass number for each isotope of a given element. The next step may be the relationship between the mass number of an element and the mass numbers of its isotopes. And that may be where the question is going. Fortunately, there is a question that considers that proposition exactly. And a link is provided to that question. Links are also provided to relevant Wikipedia articles.
Elements with same atomic number but different atomic weights are called isotopes
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.
The atomic number is the number of protons the element possesses.
The atomic number of a chemical element is identical to the number of protons.
Proton number, which is an element's atomic number, identifies an element. Each element has a unique atomic number (number of protons).
Atomic number: number of protons in a nucleus unique to an element Atomic mass number: number of protons + number of neutrons in a nucleus. May be a small range of values for a given element. Very roughly the atomic mass number is double the atomic number. For large elements it is more than double.
Atomic mass is the mass of 1 mole of the element. Atomic number is the number of protons the element has
The atomic number is the number of protons the element possesses.
The atomic number of a chemical element is identical to the number of protons.
Simply, the atomic number and the number of protons are the same. If the atomic number is 8, then there are 8 protons in the element.
The atomic number and number of protons are always the same in a normal element.
Proton number, which is an element's atomic number, identifies an element. Each element has a unique atomic number (number of protons).
Atomic number: number of protons in a nucleus unique to an element Atomic Mass number: number of protons + number of neutrons in a nucleus. May be a small range of values for a given element. Very roughly the atomic mass number is double the atomic number. For large elements it is more than double.

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.
Atomic mass is the mass of 1 mole of the element. Atomic number is the number of protons the element has
The number of protons is the atomic number.
sodium chloride is a salt, a type of compound, not an element. it has no atomic number.
the atomic number is the number of protons in a certain element. elements are arranged on the periodic table by atomic number in increasing order
