Final Answer :
D
Explanation :
The atomic number refers to the number of protons in an atom's nucleus. This determines the element to which the atom belongs as each element has a unique number of protons. Neutrons can vary among atoms of the same element, and electrons are located in the electron cloud, not the nucleus.
