Table of Contents • Gold • Helium • Hydrogen • Lead • Neon • Oxygen • Platinum • Silicon • Silver • Titanium
Gold • Found- period 6, column 11 • Classification- metal • Atomic Number- 79 • Weight-196.9655g.mol -1 • Boiling Point- 2856 ºC • Melting Point- 1064.18 ºC • Common isotope form- 18 • Discovered by- since ancient times • Atomic Symbol- Au • Uses- It is used in coinage and is a standard for monetary systems in many countries. It is also extensively used for jewelry, decoration, dental work, and for plating. It is used for coating certain space satellites, as it is a good reflector of infrared and is inert. Gold Bars
Helium • Found- period 1, column 18 • Classification-noble gas • Atomic Number- 2 • Weight-4.00260 • Boiling Point--268.93 ºC • Melting Point-<-272.2 ºC • Common isotope form- • Discovered by-Janssen • Atomic Symbol- He • Uses-as an inert gas shield for arc welding; a protective gas in growing silicon and germanium crystals and producing titanium and zirconium; as a cooling medium for nuclear reactors, and as a gas for supersonic wind tunnels. Helium Balloon
Hydrogen • Found- period 1, column 1 • Classification- noble gas • Atomic Number- 1 • Weight-1.0079 • Boiling Point- -252.87 ºC • Melting Point- - 259.34 ºC • Electron Structure- 1s1 • Common isotope form- • Discovered by-Cavendish • Atomic Symbol- H • Uses-Great quantities of hydrogen are required commercially for nitrogen fixation using the Haber ammonia process, and for the hydrogenation of fats and oils. It is also used in large quantities in methanol production, in hydrodealkylation, hydrocracking, and hydrodesulfurization. Other uses include rocket fuel, welding, producing hydrochloric acid, reducing metallic ores, and filling balloons. Hydrogen
Lead • Found- period 6, column 14 • Classification- metalloids • Atomic Number- 82 • Weight-207.2 • Boiling Point- 1749 ºC • Melting Point- 327.46 ºC • Electron Structure- [Xe]6s24f145d106p2 • Common isotope form- • Discovered by-Long known, mentioned in Exodus. • Atomic Symbol- Pb • Uses-The metal is very effective as a sound absorber, is used as a radiation shield around X-ray equipment and nuclear reactors, and is used to absorb vibration. White lead, the basic carbonate, sublimed white lead, chrome yellow, and other lead compounds are used extensively in paints, although in recent years the use of lead in paints has been drastically curtailed to eliminate or reduce health hazards Lead bottle
Neon • Found- period 2, column 18 • Classification- gas • Atomic Number- 10 • Weight- 20.179 • Boiling Point- -246.08 ºC • Melting Point- -258.59 ºC • Common isotope form- • Discovered by- Ramsay and Travers in 1898 • Atomic Symbol- Ne • Uses-Although neon advertising signs account for the bulk of its use, neon also functions in high-voltage indicators, lightning arrestors, wave meter tubes, and TV tubes. Neon and helium are used in making gas lasers. Liquid neon is now commercially available and is finding important application as an economical cryogenic refrigerant. Neon Sign
Oxygen • Found- period 2 , column 16 • Classification- noble gas • Atomic Number- 8 • Weight-15.9994 • Boiling Point--182.95 ºC • Melting Point--218.79 ºC • Discovered by-Oxygen was prepared by several workers, including Bayen and Borch, but they did not know how to collect it, did not study its properties, and did not recognize it as an elementary substance. • Atomic Symbol- O • Uses-Plants and animals rely on oxygen for respiration. Hospitals frequently prescribe oxygen for patients with respiratory ailments. Oxygen Tank
