All atoms of a given element have the same

Question

Quizplus · Accepted Answer

Atomic number is the number of protons in the nucleus of an atom and it determines the identity of the element. All atoms of a given element have the same number of protons, hence they have the same atomic number. The other options (A, C, D, E) are not true for all atoms of a given element since isotopes of the same element can have different atomic masses, number of nucleons, number of neutrons, and mass numbers.
