URGENT! plz help me T-T The compound MnO2 could either have a +4 or a +2 oxidation state on the manganese (Mn) atom. Explain how either scenario could occur.

See explanation

Explanation:

Manganese is a transition element. All transition elements have incompletely filled d orbitals which ultimately makes them to exhibit a variable oxidation state.

Manganese has electronic configuration of [Ar]4s23d5. This means that two electrons could be lost from the s orbital to yield Mn^2+. Also, two electrons could be lost from both s and d orbitals to yield Mn^4+

beta decay is the answer

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.
