c.1300, “earth, air, fire, or water,” from Old French element (10c.), from Latin elementem “rudiment, first principle, matter in its most basic form” (translating Greek stoikheion), origin unknown. Meaning “simplest component of a complex substance” is late 14c. Modern sense in chemistry is from 1813. Elements “atmospheric force” is 1550s.
- A substance that cannot be reduced to simpler substances by normal chemical means and that is composed of atoms having an identical number of protons in each nucleus.
- A fundamental, essential, or irreducible constituent of a composite entity.
- A substance that cannot be broken down into simpler substances by chemical means. An element is composed of atoms that have the same atomic number, that is, each atom has the same number of protons in its nucleus as all other atoms of that element. Today 117 elements are known, of which 92 are known to occur in nature, while the remainder have only been made with particle accelerators. Eighty-one of the elements have isotopes that are stable. The others, including technetium, promethium, and those with atomic numbers higher than 83, are radioactive. See Periodic Table.
- Mathematics A member of a set.
In chemistry, any material (such as carbon, hydrogen, iron, or oxygen) that cannot be broken down into more fundamental substances. Each chemical element has a specific type of atom, and chemical compounds are created when atoms of different elements are bound together into molecules. There are 119 chemical elements whose discovery has been claimed; 92 occur in nature, and the rest have been produced in laboratories.
