... The atomic nucleus In addition to the “discovery” of the nucleus and of the proton, Rutherford also noted the need of a “neutral” particle in the atomic nucleus, due to the disagreement between the atomic number of an atom (number of positive charges) and its mass computed in atomic mass units.

... When an object is heated it can radiate large amounts of energy as infrared radiation. We can feel this if we place a hand near, but not touching, a hot object. When an object is heated it starts to glow a dull red, followed by bright red, then orange, yell ow and finally white. At extremely high te ...

... Energy source of the Sun The energy source of the Sun lies in the fusion of four protons to one helium nucleous, as proposed by Hans Bethe in the late 1930’s. Since the binding energy per nucleon is greater in helium than in a proton by a factor 0.007 such that the mass of the four individual proton ...
