Step 1:I'll solve this step-by-step using proper LaTeX notation:
Step 2:: Identify the permanganate ion structure
- The permanganate ion has the chemical formula $$MnO_{4}^{-}
- This means we have one manganese atom and four oxygen atoms with a total charge of - 1
Step 3:: Determine the oxidation state of oxygen
- Oxygen typically has an oxidation state of $$-2$$ in most compounds
- With four oxygen atoms, the total oxygen contribution is 4 \times (- 2) = - 8
Step 4:: Calculate the manganese formal charge
- Solve for $$x$$: $$x = -1 + 8 = +7
- Oxygen contribution is - 8
Step 5:: Verify the oxidation state
- The oxidation state of manganese is indeed $$+7$$, which matches our formal charge calculation
Final Answer
The formal charge on manganese in the permanganate ion is + 7.
