The name manganese IV sulfide provides important information about the composition and charges of the ions involved in the compound. Let’s break it down:
- A: There are four manganese atoms – This statement is incorrect. The ‘IV’ in manganese IV sulfide refers specifically to the oxidation state of the manganese ion, not the number of manganese atoms present in the compound.
- B: There are four sulfur atoms – This is also incorrect. The formula does not indicate the number of sulfur atoms; it indicates the charge on the manganese ion.
- C: Each sulfur atom has a charge of 4 – This is not true. Sulfur typically has a charge of -2 in sulfide compounds, indicating that there are two electrons gained by each sulfur atom.
- D: Each manganese atom has a charge of plus 4 – This is correct. The ‘IV’ in the name signifies that each manganese atom in the compound has a +4 charge.
In conclusion, the correct interpretation of manganese IV sulfide is that the manganese has a +4 oxidation state. Therefore, the most accurate statement from the options provided is option D.
