The three nuclides, U-233, U-235, and U-238, are isotopes of uranium because they have the same number of protons per atom and A) the same number of neutrons per atom B) a different number of electrons per atom C) a different number of neutrons per atom D) the same number of electrons per atom

The three nuclides U-233, U-235, and U-238 are isotopes because they have a different numbers of neutrons. Thus, option C is correct.

Isotopes of an element can be defined as the elements with the same atomic number but different mass numbers. The atomic number can be defined as the number of electrons of an atom.

The number of neutrons in an atom has been different per atom. Thus, option A is incorrect. Option C is correct.

Thus the three nuclides U-233, U-235, and U-238 are isotopes because they have a different numbers of neutrons. Thus, option C is correct.

The correct answer is - C) a different number of neutrons per atom.

Explanation:

Isotopes of an element are the same element and same atomic number but with different atomic mass and physical properties. The difference in their atomic mass occurs due to isotopes of an element have a different number of neutrons per atom.

The number of protons and the numbers of electrons are the same in the isotopes but only change occurs in the numbers of the neutrons. In isotopes of uranium U-233, U-235, and U-238 have the same number of protons but a different number of neutrons per atom.
