G.C. Pimental has attempted to bond this element with two fluoride atoms. This element's yellow spectral lines were first observed during a solar eclipse by Pierre Janssen. Two atoms of this element can be combined to form Beryllium, and ultimately Carbon-12. This element's most common isotope does not have a triple point where gas, liquid, and solid phases coexist in equilibrium. This element forms the basis for the triple-alpha process, and it can be created by the fusion of hydrogen. For 10 points, name this element with atomic number two, the lightest of the Noble gases.
