Helium.
The atomic number represents the number of protons in an atom's nucleus, which determines the element's identity. All atoms of the same element have the same number of protons in their nucleus, hence they all have the same atomic number.
Protons. All atoms of the same element have the same number of protons in their nucleus, which defines their element and gives them their unique properties.
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.
All elements contain protons.

It describe the Number of Protons.
helium
All atoms of the same element have the same number of protons. Atoms of different elements have different numbers of protons. The number of protons determines the element.
The element with 2 more protons than oxygen is sulfur. Oxygen has 8 protons, while sulfur has 16 protons.
The nuclei of all atoms of a given element always have the same number of protons. This number is unique to each element and is known as the element's atomic number.
Helium.
All isotopes of an element have the same number of protons in their nucleus. This is what defines them as being the same chemical element. The number of protons determines the element's atomic number.
All atoms have either neutrons protons and electrons or all 3 or 2
