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.
number of neutrons
The atomic mass and the relative abundance of each naturally occurring isotope of chlorine.
The atomic number of an element is determined by the number of protons.
The identity of the element is determined solely by the atomic number, which is the number of protons.
The atomic number of an element depends on the number of protons in that element.
number of neutrons
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.
The only isotopes with atomic mass = 22 are:10Ne-22 (9%)11Na-22 (0%) not natural occurring12Mg-22 (0%) not natural occurring

In order to answer this, the number of neutrons must also be known. Subtract the number of neutrons from the mass number and the result is the atomic number. mass no. - no. of neutrons = atomic number (no. of protons)
subtract the atomic number from the mass number
An element square consists of the element's name, symbol, atomic mass, and atomic number.
