Isotopes of flerovium are varieties of atoms (and nuclei ) of the chemical element of flerovium having different neutron contents in the nucleus. At present, 5 flerovium isotopes are known and 2 more are not finally confirmed by the excited isomeric states of some of its nuclides . In nature, not one of its isotopes was found.
