The stony-iron Pallasite meteorites are not connected to the Pallas asteroid, being instead named after the German naturalist Peter Simon Pallas. The chemical element palladium, on the other hand, was named after the asteroid, which had been discovered just before the element. As with other asteroids, the astronomical symbol for Pallas is a disk with its discovery number, ②. It also has an older, more iconic symbol, ⚴ () or sometimes 🜍 (). Pallas has
Group 5 element he retracted his claim. Niobium was discovered by the English chemist Charles Hatchett in 1801. Tantalum was first discovered in 1802 by Anders Gustav Ekeberg. However, it was thought to be identical to niobium until 1846, when Heinrich Rose proved that the two elements were different. Pure tantalum was not produced until 1903. Dubnium was first produced in 1968 at the Joint Institute for Nuclear Research by bombarding americium-243 with neon-22. Dubnium was again produced at the Lawrence Berkeley Laboratory in 1970. The names "neilsbohrium" and "joliotium" were proposed for the element, but in 1997, the IUPAC decided to name
