• element

• matter

A combination of two or more substances physically blended together.

_{Homogeneous mixtures...}

• Have a uniform composition. Once the diferent components are mixed, they cannot be identified or separated from each other
• Have an irregular composition. They are formed by two or more elements that do not combine with each other. The different components maintain their characteristics.
