Question

Elements which are good catalysts and have ability to change their oxidation number are

Answer 1

Transition metals and their compounds function as catalysts either because of their ability to change oxidation state or, in the case of themetals, to adsorb other substances on to their surface and activate them in the process.

Answer 2

Answer:

Transition elements are the elements which are good catalysts which have the cappotential to change their oxidation number.

Explanation:

• Transition metals and their compounds function as catalysts because of their ability to change oxidation state.
• Transition elements (also called transition metals) are elements that have partially filled d orbitals.
• IUPAC defines transition elements as an element having a subshell partially filled with d-electrons.
