• Fissile materialNarrower topic: Fissility depends on the nucleus's isotope, not merely its chemical element.

• FleroviumNarrower topic: Known flerovium atoms differ chiefly by which radioactive isotope was produced.

• Nuclear isomerCompared with: An isomer differs in energy state, whereas isotopes differ in neutron number.

• Uranium-series datingNarrower topic: Uranium-series calculations distinguish isotopes of uranium, thorium, and their decay products.

• Absolute datingRelated: Dating systems distinguish isotopes that decay from those that accumulate.

• Thorium-232Narrower topic: The number 232 specifies thorium’s total number of protons and neutrons.

• AstatineRelated: Astatine has no stable isotopes, so its properties depend on which radioactive isotope is considered.
