Card 1 of 23

Why do transition metals exhibit variable oxidation states?

A

The 4s4s4s and 3d3d3d sub-levels are very similar in energy, and the energy required to remove successive 3d3d3d electrons increases sharply.

B

The 4s4s4s and 3d3d3d sub-levels are very similar in energy, and the energy required to remove successive 3d3d3d electrons increases gradually.

C

The 4s4s4s and 3d3d3d sub-levels are very different in energy, and the energy required to remove successive 3d3d3d electrons increases sharply.

D

The 4s4s4s and 3d3d3d sub-levels are very different in energy, and the energy required to remove successive 3d3d3d electrons increases gradually.
