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.
To determine the atomic number of an unknown element with a mass number of 22, you would need to know the number of protons in the nucleus of the element. Since the mass number is the sum of protons and neutrons, subtracting the number of neutrons from the mass number would give you the atomic number. This is because the atomic number represents the number of protons in an element's nucleus.
The atomic number, or Proton number, defines which element it is. So by definition, two different elements must have a different atomic number, or else they'd be the same element. Atomic mass is the number of protons + neutrons in the element's nucleus. Since the number of neutrons in the nucleus can vary, even within a single element (as isotopes) it is possible to have one isotope of one element sharing an atomic mass with an isotope of another element.
Almost every periodic table includes the atomic number, and even if it doesn't, you could always count.

Since the mass number is the sum of protons and neutrons, subtracting the number of neutrons (mass number) from the mass number gives you the number of protons (atomic number).
All elements that have an atomic mass of 22 are known. One example would be 22 sodium. Now, if you are talking about the atomic number of 22, that would be Titanium, which is also known.
If the atomic number of Element D is 20, then Element D is calcium (Ca). The atomic number of calcium is 20, so R would also have an atomic number of 20. This means that R would also be calcium (Ca).
Could you please re-ask your question in a better manner, because that question does not make sense. Are you trying to ask the atomic mass of the element with the atomic number of 7? or are you just stating that there is an element with the atomic number of 7? because that is not a very good question.

The element in group one with a higher atomic number than chlorine but lower atomic number than bromine is iodine. Its atomic number is 53, which is greater than chlorine's atomic number of 17 but less than bromine's atomic number of 35.
There is NO element with the Atomic No. of 238. Atomic No. only go to ~ 110. However, There is an element with ATOMIC MASS of 238, it is an isotope of Uranium NB . Atomic Number refers to #1 the position in the periodic table #2 the number of protons in the element #3 the number of electrons in the neutrally charged element. Atmoic Mass refers to the Sum total of all the protons and neutrons in the nucleus of an element. An element such as Uranium would be shown in the periodic table as [238/92]U. The two numbers indicating the Atomic Mass and the Atomic Number.
the only element with a mass number of 22 is sodium (Na) which has an atomic number of 11. This is because the atomic number only represents the number of protons in the nucleus, while the mass number represents the number of protons and neutrons in the nucleus.
could be either the atomic number or the mass number of the element, depending on what you are referring to.
Almost every periodic table includes the atomic number, and even if it doesn't, you could always count.
The atomic number of the isotopes of an chemical element is the same; only the atomic mass of the isotopes is different. Also the isotopes of an element have the same chemical and physical properties (of course with some approximation).
Atomic number is the number of protons in the nuclei of the atoms of an element. It is the number of protons that determines the atomic number. In a neutral atom, the number of electrons equals the number of protons. So in a way you could say that atomic number determines the number of electrons in a neutral atom.
The atomic mass of an element is the average mass of an atom of that element. For a gas with an atomic mass of 20, it could be calcium (Ca). Calcium has an atomic number of 20 and an atomic mass of approximately 40.08 grams per mole.
