SUMMARY
The compound As2S3 is named Arsenic trisulfide due to the presence of three sulfur atoms bonded to two arsenic atoms. This nomenclature is used despite arsenic being classified as a metalloid, which typically does not follow the non-metal naming conventions. The use of the prefix "tri-" in trisulfide distinguishes it from other arsenic sulfide compounds, such as AsS (Arsenic monosulfide) and As2S5 (Arsenic pentasulfide).
