Word History
When Russian chemist Dmitri Mendeleev devised the Periodic Table in 1869, there were 63 known elements, which he classified by atomic weight, and arranged a table listing them with vertical rows corresponding to shared chemical characteristics. Gaps in the table suggested the possibility of elements not yet discovered, and indeed elements were later discovered, or in some cases, artificially created, that filled the gaps and had the expected chemical properties. The striking correlation between the atomic weight of an element and its chemical properties was later explained by quantum mechanical theories of the atom. The weight of an atom of any given element depends on the number of protons (and neutrons) in its nucleus, but the number of protons also determines the number and arrangement of electrons that can orbit the nucleus, and it is these outer shells of electrons that largely determine the element's chemical properties.
Cultural definitions for element
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.
