It is about the atomic numbers. The total of protons.
It tells you (1) how many protons are in the element, and (2) what the element is since all atoms of an element will have the same number of protons.It's D. The number of protons in its atoms.It tells how many protons/electrons that element has.
atomic mass is the answer
The atomic number of an element tells you how many protons an atom of that element contains. This number is unique to each element and is found on the periodic table. The number of protons in an atom determines the element's identity.
The Atomic number tells you the number of protons in the nucleus of atoms of that element.
The subscript, the little number below and after the element, tells how many atoms are in a single molecule.

The atomic number of an element is the number of protons in the nuclei of its atoms. Each element has a unique atomic number.
number of protons in the atoms tells us to what chemical element atoms belongs. in other words :different number of protons means different element. also protons together with neutrons make most of the atoms weight.
That would be subscript.
The subscript number after a chemical symbol indicates how many atoms of that element are present in a single molecule of the compound.
In a molecular formula, the subscript tells us the number of atoms of the element that are present in one molecule of the compound. For instance,H2O tells us that there are two hydrogen and one oxygen atom per molecule of water. As for ionic compounds, it tells us the number of atoms present in one formula unit of the compound.
The Atomic Mass of an element tells you what the mass of one mole (6.022 x 1023 atoms) of the element is. It sort of tells you the number of protons & neutrons in the atom, but that is not necessarily precise.
