In which oxidation state does manganese exhibit the highest oxidation state?

In which oxidation state does manganese exhibit the highest oxidation state?

Step 1: Understand what oxidation state means. It refers to the charge of an atom in a compound.
Step 2: Identify manganese (Mn) on the periodic table. It is a transition metal.
Step 3: Learn that manganese can have multiple oxidation states, ranging from -3 to +7.
Step 4: Find out which compound contains manganese in its highest oxidation state.
Step 5: Discover that the permanganate ion (MnO4-) is a common compound of manganese.
Step 6: Note that in the permanganate ion, manganese has an oxidation state of +7.
Step 7: Conclude that +7 is the highest oxidation state exhibited by manganese.
