Transition Metal. The metal valence population indicates that there is a further charge transfer from the 7s atomic orbitals to the 6d one (see Table SI). I think maybe you are stuck on the concept of ions and charge. Rutherfordium Unlike uranium-235, it is non-fissile, which means it cannot sustain a chain reaction in a thermal-neutron reactor.However, it is fissionable by fast neutrons, and is fertile, meaning it can be transmuted to fissile plutonium-239.
