An atom is the tiniest piece of an element that is made up of a nucleus that contains a combination of neutrons, protons, and one or more electrons. A molecule is the tiny physical portion of an element or compound that is made up of one or more like atoms and has two or more different atoms in a compound. A compound is the product of two or more chemical elements that have been attached together.
Two examples of atoms are Hydrogen, H, and Oxygen, O. Hydrogen and Oxygen are single particle elements. These elements consist of at least one proton. Two examples of moles are Nitrous Oxide, N2O and Water H2O. These elements are correctly identified as molecules because they are a combination of two single elements that are attached together
