Its mass is tiny compared to other subatomic particles. A subatomic particle with a negative elementary electric charge. A species of atoms having the same number of protons in their atomic nuclei (i.e. the same atomic number, Z). There are 118 elements that have been identified. Hadronic subatomic particles composed of one quark and one antiquark, bound together by the strong interaction. An elementary particle and a fundamental constituent of matter. Quarks combine to form composite particles called hadrons, the most stable of which are protons and neutrons. A chemical substance consisting of two or more different chemically bonded chemical elements, with a fixed ratio determining the composition. A molecule is the smallest particle in a chemical element or compound that has the chemical properties of that element or compound. Any particle that is made from quarks, anti-quarks and gluons.
