I think it’s Cr3+ because best oxidizing agent means best reduction one (gains electrons). Since Cr3+ has 3 less electrons, I assume that one would gain electrons the easiest.
Answer: The octet rule is a chemical rule of thumb that reflects the observation that main group elements tend to bond in such a way that each atom has eight electrons in its valence shell, giving it the same electronic configuration as a noble gas.
