Question

Find the IUPAC symbol for the element Cobalt?
with solution

Answer 1

Answer:

The name derives from the German Kobold for "evil spirits" or "goblins", who were superstitiously thought to cause trouble for miners because the mineral contained arsenic that injured their health and the metallic ores did not yield metals when treated with the normal methods. Cobalt was discovered in 1735 by the Swedish chemist Georg Brandt.
