Palladium | Chemical elements

Palladium was discovered in 1803 by William Wollaston. Palladium’s name derives from the Greek word "pallas" which is the Greek goddess of wisdom and the name of an asteroid. Palladium’s melting point is at 1552.0 °C (1825.15 K, 2825.6 °F) and its boiling point is at 2927.0 °C (3200.15 K, 5300.6 °F).
