Element Argon Ar, Noble Gas. obtained from chemical compounds, in having a somewhat greater density.
Element Chlorine, Cl, Hallogen.
Element Helium, He, Noble Gas. In 1871 Lockyer explained it by the presence of a new element in the Sun. On 26 March 1895 British chemist William Ramsay isolated helium. Observed in the spectrum of the Sun.
Element Neon, Ne, Noble Gas. Was discovered in 1898 by Scottish chemist William Ramsay and English chemist Morris W. Travers, when Ramsay chilled a sample of the atmosphere until it became a liquid, then warmed the liquid and captured the gases as they boiled off. The spectral analysis showed the presence of new three gases which were krypton, xenon, and neon. I should like to call it Novum. Is supplied by natural waters.
Element Oxygen, O, Non Metal. Joseph Priestley was generally acknowledged as the discoverer of oxygen. By heating it via the sun rays focused on it by powerful lens. However Priestley first did not realize that he discovered a new substance. He supposed that he just separated one of the components. Priestley informed Antoine Laurent Lavoisier about his discovery. Is the most abundant element on the Earth; i.
