How many oxidation states do most d-block elements have?
A) 0
B) 1
C) More than one
D) It depends on the ligands to which it is bound.
E) It depends on the number of unpaired d-electrons in the element.

Question

Quizplus · Accepted Answer

Most d-block elements have multiple oxidation states due to the availability of d-orbitals for bonding with different numbers of electrons. This is known as variable valency or variable oxidation state. The specific number of oxidation states is dependent on factors such as the electronic configuration of the element, the nature of the ligands it is bound to, and the strength of the covalent bonding between the element and the ligands.
