The 21-centimeter line is cased by hyperfine transitions of this element. Two atoms of this element are involved in a chain reaction releasing neutrinos and gamma rays, and the Teller-Ulam design was for a device using this element. Its antimatter counterpart was created and confined at CERN in November 2010, and the visible spectral line emissions of this element give rise to the Balmer series. The Bohr model was originally conceived to describe an atom of this element, which is converted into helium in stars. For 10 points, name this lightest element with an atomic number of 1.
