unusual facts about highly charged ion



Coronium

It was not until the 1930s that Walter Grotrian and Bengt Edlén discovered that the spectral line at 530.3 nm was due to highly ionized iron (Fe13+); other unusual lines in the coronal spectrum were also caused by highly-charged ions, such as nickel, the high ionization being due to the extreme temperature of the solar corona.
