Coronium Coronium, also called newtonium, was the name of a suggested chemical element, hypothesised in the 19th century. The name, inspired by the solar corona, was given by A. Gruenwald in 1887. A new atomic thin green line in the solar corona was then considered to be emitted a new element unlike anything else seen under laboratory conditions. Because of this it was also mis-classified as Iron Line Number 1474.
