Elements, Compounds, and Mixtures

By Oliver Smith

Everything around us is made of atoms: the clothes we wear, the air we breathe, the water we drink, and ourselves. These atoms form roughly 92 naturally occurring elements on Earth, which then form everything we know. The result of these combinations can come in the form of elements, compounds, or mixtures, depending on their atomic makeup. While compounds and mixtures can be separated through a variety of techniques, elements cannot, as they exist in the purest form possible. Introducing students to atoms, elements, compounds, and mixtures will provide them with an important foundation that will help them grasp more complex concepts in chemistry.
