AI overview

A molecule is the smallest unit of a substance that retains its chemical properties, made up of atoms bonded together—as shown in microscope images of molecules like PTCDA (with five carbon rings) and pentacene (with five linked carbon rings). Molecules matter because they are the basic building blocks of all matter around us, determining the properties and behavior of the materials and substances we interact with every day.
