Explanation:
Atoms are the smallest unit of matter. Atoms of isotopes of the same element contain the same number of protons.
<h3>What are isotopes?</h3>
Isotopes are atoms of the same element which have different numbers of neutrons but the number of protons and electrons remains same.
As the isotopes of the atom have the same number of protons, so, their atomic number will also be the same.
Thus, it can be concluded that atoms of isotopes of the same element contain the same number of protons.
