What is the chemical formula for tin(IV) sulfide?

The chemical formula for tin(IV) sulfide is represented as SnS2. In this case, the Roman numeral IV indicates that tin has a charge of +4. Sulfide, derived from sulfur, has a charge of -2.

To determine the correct ratio of tin to sulfide in the compound, we need to balance the charges. Since each sulfide ion contributes a -2 charge, two sulfide ions would provide a total charge of -4. To balance this negative charge, we require one tin ion with a +4 charge. Thus, one tin ion (Sn^4+) and two sulfide ions (2 S^2−) come together to form SnS2.

This balance of charges ensures that the compound is electrically neutral, which is a fundamental principle in chemical formula writing. Therefore, the formula SnS2 correctly represents tin(IV) sulfide.
