As the electrons fall back to lower energy levels they release the energy they absorbed in set amounts called quanta. The energy that is released as electrons fall from higher to lower energy levels has a characteristic ...

... Rutherford said it was “as if you had fired a 15-inch (artillery) shell at a piece of tissue paper and it came back and hit you.” Why did this happen? Rutherford reasoned that the fast-moving particles must be repelled by some powerful force within the atom. Also, whatever caused this repulsion must ...
