context: Neon is one of the common elements in the universe, as it comes fifth in terms of the abundance of chemical elements in the universe in terms of mass, after hydrogen, helium, oxygen and carbon. Neon stable isotopes are produced in stars, where the 20Ne isotope is formed by the interaction of the helium and oxygen fusion in the alpha process, which requires temperatures above 100 Mg.
question: What is the arrangement of neon gas in terms of the abundance of chemical elements in the universe in terms of mass?
