The electronic structure and properties of the actinides in unusual oxidation states have been examined within the framework of quantum-chemical ideas. Hartree- Fock atomic calculations for the actinide series, and molecular orbital calculations for the octahedral oxyanions of uranium, neptunium, plutonium, and

Traversing the series r(M3+) steadily decreases – the lanthanide contraction. Difficult to separate and differentiate, e.g. in 1911 James performed 15000 recrystallisations to get pure
