Most atoms have more than one isotope, meaning that they have a variable number of neutrons.
Uranium-235 is an isotope that is present in a 0.7% natural abundance. It is used in nuclear reactors as a source of fuel.
Carbon-14 is used to date artifacts because the amount of carbon-14 in a sample decays at a slow, predictable rate and is not replenished by the environment.
Hydrogen-2, or deuterium, is used to make solvents that will not interfere with a certain type of chemical analysis known as nuclear magnetic resonance.
Americium-241 is used in smoke detectors.
Numerous radioactive isotopes are used in radiation therapy for various cancers.
