The document discusses the composition and properties of matter at the atomic-molecular level. It describes the basic units that make up all matter including atoms, molecules, and crystals. Atoms are the smallest units that cannot be broken down further through chemical means. Molecules are combinations of two or more atoms held together by chemical bonds. Crystals are solid arrangements of atoms, molecules, or ions in a repeating pattern throughout three-dimensional space.
