Products Price list Services About company Contacts Documentation The history of the discovery of helium For the first time the chemical element helium was discovered in 1868 in India by P. Jansen while studying a solar eclipse. Spectral analysis of the solar chromosphere revealed a bright yellow line, originally assigned to the spectrum of sodium, but in 1871 J. Lockyer and P. Jansen proved that this line does not belong to any of the elements known on Earth. J. Lockyer and E. Frankland named the new element helium (from the Greek "helios" - "sun"). At the time, helium was thought to be a metal. Only after almost a quarter of a century, helium was discovered on Earth. In 1895 W. Ramsay and the Swedish chemists P. Cleve and N. Lengle established that helium is released when the mineral cleveite is heated. A year later, G. Keizer discovered an admixture of helium in the atmosphere, and in 1906 helium was found in the natural gas of the Kansas oil wells. In the same year, E. Rutherford and T. Royds established that the alpha particles of radioactive elements are helium nuclei.
