Copper
Cu63.55 g/mol Calculated
Also called Tatum-T and Cu.
One of the first metals people smelted, more than seven thousand years ago, and the reason electricity is affordable to move. It is also a trace nutrient and a surface that kills bacteria. Element 29. Found in chocolate, cocoa, nuts, shellfish, and mushrooms.
