Detailed description on the Element Iridium.

iridium field of study Iridium is a tinny element of the platinum group with the atomic number 77 , atomic mass 192.2, boiling lay at nigh 44oo degrees celcuis (7952 degrees farinheight), and a melting point of 2450 c (4442 f) the irduims symbol is Ir. Iriduim was ascertained by a British pharmacist by the shape Smithson Tennat (1761-1815) in 1804 and received its name from the opalescent nature of nearly of its compounds. it is an exceedingly rargon admixture, ranking sixtyfirst in sanctify of abundance of the elements in the crust of the earth and is free-base in alluvial deposits alloyed with platinum as platin atomic number 77, or with osmium as osmiridium. Iridium is a white, brittle , extremely life-threatening metal. its specific gravity is exceeded only by that of osmium, which is a portion of one percent denser. it is extremely inhert chemically resisting steady the put through of aqua regia (q.v.) in its chemical compounds it forms double and trivalent salts. It is use chiefly as an alloying material for platinum; the alloy which contains about 10 percent iridium, is far harder than thoroughgoing(a) platinum. Platinium-iridium alloys containing larger percentages of iridium are used in the devising precision instruments, such(prenominal) as: surgical tools. pen points, and standard weights and lenghts. Iridium has a sensationalistic cast to it. salts of iridium are highly colored. it is the most erosion resistant metal known, not attacked by any acid, solely is attacked by molten salts. there are two inwrought isotopes of iridium, and 4 radioisotopes. The most stable organism Ir-192 with a half-life of 73.83 days. Ir-192 decays into platium, while the other radioisotopes decays onto osium. Iridium metal is generally non-toxic payable to its relative unreactivity but iridium compounds should be considered highly toxic. your report was qu ite concise and succinct.
