sulfide
Rotten-egg gas type
A sulfide is a chemical compound containing sulfur bonded to a metal or other element.
Hydrogen sulfide gives rotten eggs their smell.
Metal sulfides occur naturally as ores—iron pyrite, lead galena, zinc sphalerite.
In chemistry, sulfide also refers to the S²⁻ ion.
British spelling: sulphide.
