Rocks & Minerals

5 Atoms & Elements • Rocks are made up of minerals. • Minerals are composed of elements. • Elements can be separated into atoms. • Atoms are composed of protons, neutrons, and electrons. • Each element has a unique atomic number that represents the number of protons in its nucleus. • Elements in the foods we eat originate in the rocks of Earth's crust.
