Manganese Carbonate and Polyatomic Ions

The video tutorial explains how to write the formula for manganese six carbonate. It begins by identifying the element symbol for manganese and its charge, followed by an explanation of the carbonate ion as a polyatomic ion with a specific charge. The tutorial then demonstrates how to balance these charges to achieve a neutral compound, resulting in the formula Mn(CO3)3. The video concludes with a summary of the process and the final formula.
