Look up in an 'Isotope'-table.
The only isotopes with Atomic Mass = 22 are:
10Ne-22 (9%), or
11Na-22 (0%) not natural occurring, or
12Mg-22 (0%) not natural occurring.

What information could you use to determine the atomic number of unknown element that has a mass number of 22?
number of neutrons
Which particle determines the atomic number of an element?
The atomic number of an element is determined by the number of protons.
What information could you use to determine the atomic number of an unknown element that has the mass number of 22?
If you don't know the element, then you would need the number of electrons in a neutral atom of the element, which would be the same as the atomic number.
Which mass number or atomic number determine what element an atom is?
The identity of the element is determined solely by the atomic number, which is the number of protons.
What information was used to assign the atomic number to a particular element?
The atomic number of an element depends on the number of protons in that element.
How do you determine neutrons in element?
subtract the atomic number from the mass number
Is the element determine by the number of protons?
The atomic number is equal to the number of protons.
What information could you use to determine the atomic number of an unknown element that has a mass number of 22?
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.
Determine the number of protons?
The number of protons is equal to atomic number and the number of electrons (for a neutral atom).
What do the protons do?
The number of protons determine the atomic number of an element. There are the same amount of protons as electrons in a regular element.
Do electrons determine what kind of element an atom is?
The number of protons determine the element. It is equal to the atomic number. The number of electrons is equal to the number of protons only of the atom is neutral.
How do you determine how many protons are in an element?
Experimentally, I'm not sure, but I know you can look at your periodic chart, the large number over the symbol of each element is teh number of protons in that element.
