Aluminum has only one oxidation state, while chromium has several. Which of the following is the best explanation for this difference?
A. Electrons in the d orbitals of Cr may or may not be used to form bonds.
B. Electrons in the p orbitals of Cr may or may not be used to form bonds.
C. Electrons in the d orbitals of Al may or may not be used to form bonds.
D. Electrons in the p orbitals of Al may or may not be used to form bonds.
I used process of elimination to find the answer to the question above. The answer is A. Is there a better explanation. How else can it be solved? Please provide an explanation.
Much thanks!!!
