When atoms come together by transferring or sharing electrons, they form chemical bonds that hold them in a definite arrangement. This creates a substance made from two or more elements in fixed proportions, known as a compound. The key idea is that the elements are chemically bonded, giving new properties that are different from the individual elements.

An element is just a pure type of atom. A mixture is a physical combination of substances that are not bonded, so its components can usually be separated by physical means. A solution is a special kind of mixture where one substance dissolves in another at the molecular level, but the components are not chemically bonded to each other. Therefore, the term that describes two or more elements bonded together to form a new substance is a compound.
