The elements in potassium sulphide are potassium (K) and sulfur (S). Potassium is a metal, while sulfur is a non-metal. Potassium sulphide is an ionic compound formed by the combination of potassium cations and sulfide anions.
iron and sulphur
The metal is lead. Galena is lead(II) sulphide.
Lead nitrate has the formula PbNO3 Pb is Lead N is Nitrogen O is Oxygen, so there are three elements present.
Iron sulfide (FeS) consists of two elements: iron (Fe) and sulfur (S).
iron and sulfur
Potassium sulphide (or sulfide to use the modern spelling) is made of potassium and sulfur. The -ide ending tells you that there are only two elements there.
