Say what? Helium is pronounced as HEE-lee-em. Helium, the second most abundant element in the universe, was discovered on the sun before it was found on the earth. Pierre-Jules-CÃ©sar Janssen, a French astronomer, noticed a yellow line in the sun's spectrum while studying a total solar eclipse in 1868.
In the nucleus, the two protons and two neutrons are depicted in red and blue. This depiction shows the particles as separate, whereas in an actual helium atom, the protons are superimposed in space and most likely found at the very center of the nucleus, and the same is true of the two neutrons. Thus, all four particles are most likely found in exactly the same space, at the central point.
