Lawrencium is the final member of the actinide series. Neon is used in some plasma tube and refrigerant applications but has few other commercial uses. . Finally, in 1898 at University College, London, Ramsay and his colleague, Morris Travers modified an experiment they tried previously, they allowed solid argon surrounded by liquid air to evaporate slowly under reduced pressure and collected the gas that came off first. Well, using the Ideal Gas Law, the molar volume at standard temperature and pressure (and the standards change across each syllabus), is 22.4*dm^3 at a pressure of 1*atm, and a temperature of 273*K. Would this gas be denser than oxygen or nitrogen? [20] The intense color and vibrancy of neon equated with American society at the time, suggesting a "century of progress" and transforming cities into sensational new environments filled with radiating advertisements and "electro-graphic architecture".[21][22]. Examples: Fe, Au, Co, Br, C, O, N, F. You can use parenthesis () or brackets []. It has over 40 times the refrigerating capacity (per unit volume) of liquid helium and three times that of liquid hydrogen. That was Victoria Gill with the story of neon.
