What is the equation when you combine aluminum and sulfur?

Thank you nomenclature. The answer is Al2S3. Aluminum sulfide is the compound's name. The formula comes due to the oxidation levels of aluminum, with a +3, and sulfur, with a -2. read more

Aluminium is in group 13, so it has a valency of 3. Sulfur is in group 16, so it has a valency of 6. The symbol for aluminium is ‘Al’, and the symbol for Sulfur is ‘S’. We can apply the ‘swop-and-drop’ method here. The equation that we got would be Al3S6. If we ‘swop-and-drop’ that, it would become Al6S3. Therefore, this is the final equation. read more
