Answer:
Four Hydrogen nuclei (composed of one proton each) are glued together to make one Helium nucleus which has two protons and two neutrons. When this happens two protons are changed into two neutrons and huge amounts of energy is released. The name Helium comes from the Greek work "helios" which means Sun.
