Silver | Chemical elements

Silver has been known since ancient times. Silver’s name derives from the old English word "seolfor" but its symbol derives from the Latin word "argentum" which means "silver". Silver’s melting point is at 961.93 °C (1235.08 K, 1763.474 °F) and its boiling point is at 2212.0 °C (2485.15 K, 4013.6 °F).
