Protons
The atomic number of an element is determined by the number of protons within it's nucleus.
The atomic number of an atom is determined by the number of protons it has.
Atomic masses are determined by mass spectrometry. The atomic number is identic with the number of protons in the atom - depends on position in the periodic table.
The number of protons in each element is determined by the atomic number of the element. The atomic number corresponds to the number of protons in the nucleus of an atom. This number is unique to each element and is determined by the arrangement of electrons and protons in the atom.
The identity of an element is determined by the number of protons in the nuclei of its atoms. This is the atomic number of an element.
By subtracting the atomic mass and atomic number
the atomic number is determined by the number of protons in a nucleus.
The atomic number of an element is determined by the number of protons in the nucleus.

The Atomic Number
The atomic number is determined by how many protons are in the atom's nucleus.
You think probable to atomic number, equal to the number of protons in the atomic nucleus.
