Bohr’s model required only one assumption: The electron moves around the nucleus in circular orbits that can have only certain allowed radii. Atomic energy or energy of atoms is energy carried by atoms. The term originated in 1903 when Ernest Rutherford began to speak of the possibility of atomic energy. H. G. Wells popularized the phrase "splitting the atom", before discovery of the atomic nucleus.
