While you may have some incandescent bulbs lying around, once they're gone, they will be gone forever. And you probably won't mourn their inefficiency; since about 90 percent of the energy produced in the bulbs is actually heat instead of light, they are huge energy wasters. While they generally last about 1,500 hours, this is still only a fraction of the lifespan of CFLs. These are lit by an electric current sent through a tube that contains argon and a small amount of mercury gases. These gases generate invisible ultraviolet light, which commingles with a fluorescent coating on the inside of the tube to produce light.

The correct answer is Sir Ernest Rutherford.
One of the first findings on atomic energy theory was reached in 1911 by Rutherford, who became known as the father of nuclear physics.
He discovered that the mass of the atom was concentrated in its nucleus, and proposed that the nucleus has a positive charge and is surrounded by negatively charged electrons, which had been discovered in 1897 by J. J. Thomson.
His theory was complemented in 1913 by Niels Bohr, who placed the electrons in definite shells or quantum levels.
