What Is An Element, Mixture And Compound? | Properties of Matter | Chemistry | FuseSchool
FuseSchool - Global Education・5 minutes read
Elements, mixtures, and compounds have specific characteristics that differentiate them; iron and sulfur are proven to be distinct elements through tests, while a mixture of the two retains individual properties and can be physically separated, contrasting with the compound iron2 sulfide formed by heating the mixture, which behaves differently in tests and is not magnetic.
Insights
- Elements are fundamental substances that cannot be further broken down, while mixtures consist of multiple substances without fixed ratios, and compounds are combinations of elements chemically bonded.
- Iron and sulfur, when tested individually, exhibit distinct properties, confirming they are separate elements. However, when mixed and heated, they form a compound with altered characteristics, demonstrating the transformation from a mixture to a compound through a chemical reaction.

Element, Mixture, Compound: Iron and Sulfur Experiment
- An element is a substance that cannot be broken down further, a mixture is two or more substances mixed without fixed proportions, and a compound is two or more elements chemically combined.
- Iron and sulfur are tested separately, with iron reacting to acid and being magnetic, while sulfur shows no reaction and is not magnetic, proving they are different elements.
- A mixture of iron and sulfur is tested, showing that the components retain their individual properties and can be separated physically, while a heated mixture forms the compound iron2 sulfide, which behaves differently in tests and is not magnetic.
