What does a 3+ oxidation number indicate in terms of electrons?

The iron ion Fe3+, for example, has an oxidation number of +3 because it can acquire three electrons to form a chemical bond, while the oxygen ion O2− has an oxidation number of −2 because it can donate two electrons. …

Why does manganese show oxidation state?

Hint: Manganese has 7 electrons in its valence shell. These electrons are present in the s and d subshell. Manganese can lose these electrons and show variable oxidation states.
