The physicochemical properties of actinide metals confirm the presence of band-like 5f electrons up to Pu. The participation of these 5f electrons in the metallic bond is assumed to begin with Pa. In the first half of the actinide series, 5f electrons are similar to d electrons in typical transition metals: the 5f electron orbitals are more extended than 4f orbitals; for the light actinides, 5f electrons are delocalized and hybridized in a rather large band with 6d and/or 7s electrons. Starting with Am, te 5f electrons are localized again, like 4f electrons in the lanthanides.
