Why the first half of the actinoids series shows higher oxidation states?
Due to filling of electrons from 5f to 6d
Due to filling of electrons from 4f to 5d
Due to filling of electrons from 4f to 6d.
Due to filling of electrons from 5f to 5d.
As 5f orbitals are not as shielded as 4f the electrons are easily removed and variable oxidation states happen for the first half of actinoids.
