Flashcards
Compound
Compound
A pure substance made up of two or more elements chemically combined in a fixed ratio. For example, water (Hâ‚‚O) is a compound made up of hydrogen and oxygen.
Element
Element
A pure substance that cannot be broken down into simpler substances by chemical means. It's made up of only one type of atom. For example, gold (Au) is an element.
Mixture
Mixture
A substance consisting of two or more substances mixed together, but not chemically combined. Components can be separated by physical means. For example, salt water is a mixture of salt and water.
