ANSWER:Step 1 of 3
Element is the simplest substance that cannot be further broken down to simpler substances. It has only one type of atom.
Compounds are the combination of two more different elements chemically combined together. They have two more types of atoms. They can be decomposed into simpler substances.
Mixtures have constituents in variable proportions. They have the same properties as the constituents. The constituents can be separated by physical methods.
