Which element was the first to be discovered using spectroscopy?
Quick Answer
Cæsium and rubidium were among the first elements discovered by spectroscopy in 1860, with cæsium identified first.
The Full Story
Cæsium is often credited as the first element discovered by spectroscopy, identified in 1860 by Robert Bunsen and Gustav Kirchhoff. Rubidium was also discovered by the same method shortly afterward that same year. Spectroscopy allowed scientists to detect unique colored lines in light emitted by heated substances, revealing elements that had not been isolated before. This was a major turning point in analytical chemistry.
