Question

If helium had exactly the same mass as four hydrogen atoms, the luminosity o f the sun would be

Answer 1

Hydrogen has an atomic mass of about 1 and It contains one proton, orbited by a single electron. Helium has an atomic mass of approximately 4 and contains of 2 protons and 2 neutrons, orbited by 4 electrons. But all of this is irrelevant because luminosity is related to gravity, and that mass would identical, luminosity would be near identical. *insert luminosity relation equation here*
