The element with a mass number of 37 is chlorine (Cl).
You actually just answered your own question. The Isotope Ar-37 has a mass of 37. Most elements and Isotopes are commonly phrased like "Element-Mass"
The mass number for argon-37 is 37. It is calculated by adding the number of protons and neutrons in the nucleus of the argon atom.
Rubidium is a metal element. Mass number of it is 85.
The mass number of an isotope is the sum of protons and neutrons in its nucleus. In this case, the symbol 37 refers to the total number of protons and neutrons, which means the mass number of the isotope 37-17Cl is 37.
The atomic number of an element is the number of protons in the nucleus of each atom of the element. Mass number is a property of a particular isotope of the element rather than of the element itself: The mass number is the sum of the numbers of protons and neutrons in the nucleus of each atom of the isotope.
The mass number is the amount of protons and neutrons in an element. The atomic number is equal to the amount of protons. Therefore to get the number of protons from the given information, you would subtract 37 from 72 which gives you 35 protons aka its atomic number!

Rubidium is a metal element. Atomic mass of it is 85.46.
Atomic number is unique to an element. Since both Chlorine-35 and Chlorine-37 has atomic number of 17, they are both Chlorine. However they have different atomic mass (caused by different number of neutrons in the atom) thus they are called isotope.

Sodium is a metal element. Mass number of it is 23.
The atomic weight (not mass !) of an element is the weighted average mass of the naturally occurring isotopes.Example: the atomic weight of chlorine is 35.45. Chlorine is naturally composed of chlorine-35 at 75.76% and the rest chlorine-37. Therefore, the mass of any sample must be due to (75.76 x 35 + 24.14 x 37)/100The mass number of an element is the number of protons and neutrons of that isotope added together. In the above example there were two isotopes, one had a mass number of 35 and the other 37. Chlorine has 17 protons, so it is easy arithmetic to calculate the number of neutrons in each isotope.
Vanadium is a metal element. Mass number of it is 51.
Magnesium is a metal element. Mass number of it is 24.
Copper is a metal element. Mass number of it is 64.
