Platinum
Pt (194.964785)
Platinum, also known as pt, is a member of the class of compounds known as homogeneous transition metal compounds. Homogeneous transition metal compounds are inorganic compounds containing only metal atoms,with the largest atom being a transition metal atom. Platinum can be found in a number of food items such as white cabbage, sunburst squash (pattypan squash), potato, and broccoli, which makes platinum a potential biomarker for the consumption of these food products. Platinum can be found primarily in blood, cerebrospinal fluid (CSF), saliva, and urine. Platinum is one of the least reactive metals. It has remarkable resistance to corrosion, even at high temperatures, and is therefore considered a noble metal. Consequently, platinum is often found chemically uncombined as native platinum. Because it occurs naturally in the alluvial sands of various rivers, it was first used by pre-Columbian South American natives to produce artifacts. It was referenced in European writings as early as 16th century, but it was not until Antonio de Ulloa published a report on a new metal of Colombian origin in 1748 that it began to be investigated by scientists . Platinum is a rare, dense, malleable, ductile, precious, gray-white transition metal, that is highly resistant to corrosion. Platinum is used in catalytic converters, laboratory equipment, electrical contacts and electrodes, platinum resistance thermometers, dentistry equipment, and jewelry.
