Best Answer

Isotopes are atoms of the same element but with a different number of neutrons.

Example for the isotope 228 of uranium:
- uranium-228
- U-228

-- 22892U

What determines the different isotopes of an atom?

The isotopes of an atom are defined by the number of neutrons their nuclei have for their fixed number of protons. However, I wouldn't say that neutrons are solely responsible for the presence of isotopes because isotopes also depend on the existence of many other particles such as protons, quarks and gluons. Neutrons certainly are responsible for the way we label isotopes, though.
