Helium is the second most common element in the universe, and the lightest of the inert gases. Unlike helium-4, the most common isotope of helium, which contains two protons and two neutrons, helium-5 is a radioactive isotope of helium which contains one extra neutron.To...
Hydrogen's place in the universe and astronomical sciences
By: Effie Moore Salem
Hydrogen is more plentiful in our universe than all other chemicals; it makes up three-fourth of all mass.Helium is formed from the activity of the stars when their hydrogen atoms interact while in the process of forming energy. Helium, thus, is the by product...
