Chemistry & Physics.–.any substance that cannot be separated into different substances except by nuclear.disintegration. Elements in the Periodic Table.(see 'Periodic Table of the Elements' in an encyclopedia and under 'element' in a dictionary, see the Chemical Element Table for a list of 100 of the elements).are ranked by atomic number, as determined by the specific number of protons an element may have. Any more than 100 protons and their combined repulsive forces would disintegrate the atom. The elements exhibit designed structure. 

A single element can exist as several isotopes. Each element has a specific number of protons. Russian born physicist George Gamow believes that all elements came into existence at the same time the Universe did. Cosmologist Fred Hoyle at Cambridge University, believes to the contrary that the elements became synthesized in stars, but the fact that there is far too much deuterium in the Universe, tends to dispute that part of Hoyle's theory
