Smithson Tennant
Iridium/Discoverers
Smithson Tennant, the primary discoverer, named iridium after the Greek goddess Iris, personification of the rainbow, because of the striking and diverse colors of its salts. Iridium is one of the rarest elements in Earth’s crust, with annual production and consumption of only three metric tons.
What is the family name for iridium?
platinum family
Iridium, a metal of the platinum family, is white (similar to platinum) but with a slight yellowish cast. Because iridium is very hard and brittle, it is hard to machine, form, or work.
Is iridium a real element?
Iridium is a chemical element, and one of the transition metals on the periodic table. Iridium appears as symbol Ir on the periodic table and has an atomic weight of 192.217 and a density of 22.56 g/cm³, making it the second-densest known element.
What is the origin of Silver’s name?
Origin of name : from the Anglo-Saxon word “siolfur” meaning “silver” (the origin of the symbol Ag comes from the Latin word “argentum” meaning “silver”).
Is iridium more expensive than gold?
Iridium, which is also used in spark plugs, has climbed to $6,000 an ounce, according to Johnson Matthey Plc data. That makes it more than three times more expensive than gold.
Is silver a boy or girl name?

What was Sodiums original name?
Natrium
Sodium – Natrium (Na) Sodium’s Latin name, ‘natrium’, derives from the Greek ‘nítron’ (a name for sodium carbonate). Its original source is likely to be the Arabic work ‘natrun’. A number of modern languages still call the element natrium instead of sodium, and it’s this name that its chemical symbol, Na, comes from.
Can I touch iridium?
Unlike some radioactive isotopes, iridium-192 loses its potency quite quickly. No respectable dirty-bomb maker would touch it.”
How did the element iridium get its name?
The element was discovered in 1803 in the acid-insoluble residues of platinum ores by the English chemist Smithson Tennant; the French chemists H.-V. Collet-Descotils, A.-F. Fourcroy, and N.-L. Vauquelin identified it at about the same time. The name iridium, derived from the Greek word iris (“rainbow”),…
