With arsenic this element is found in the mineral sperrylite, which is associated with nickel ores in Sudbury Basin. Adam's catalyst is an oxide of this element that converts to this element's "black" form. This element was used by Barnett Rosenberg 
With arsenic this element is found in the mineral sperrylite, which is associated with nickel ores in Sudbury Basin. Adam's catalyst is an oxide of this element that converts to this element's "black" form. This element was used by Barnett Rosenberg in the electrodes for an experiment involving E Coli and electric field, and this element is found in the cis formation linked to two chloride ions and two ammonia groups in an (*) anticancer drug that crosslinks cellular DNA, leading to apoptosis. Along with palladium and rhodium, this element is commonly used in catalytic converters. For 10 points, name his noble metal with atomic number seventy eight and symbol Pt.
