Bohr’s Atomic Model Following the discoveries of hydrogen emission spectra and the photoelectric effect the Danish physicist Niels Bohr 1885 – 1962 proposed a new model of the atom in 1915 Bohr proposed that electrons do not radiate energy as they orbit the nucleus but exist in states of constant energy which he called stationary states
