Morphology
iron + disulfide
The term follows systematic chemical naming: combining 'iron' with 'disulfide' straightforwardly denotes a compound of iron and two sulfide groups, so the overall meaning is directly derivable from its parts. Although domain-specific vocabulary, the morphological composition is compositional and regular (as in many languages' chemical nomenclature), making it understandable to a learner who knows both constituents.
Etymology
The noun iron disulfide actually tells you it is made of one iron atom and two sulfur atoms. Its common form is the mineral pyrite, often called 'fool's gold' because it shines like real gold and can even make sparks when struck, so the name helps you remember both its parts and its shiny, metal-like nature.
