WebJul 7, 2024 · Bohr’s Model of the Atom. Although Rutherford’s model was a breakthrough, it had some flaws, the main one being the way it described the motions of the electrons. In 1913, Danish physicist Niels Henrik David Bohr improved Rutherford’s model by reasoning that if electrons were moving like planets, their orbits would be very unstable.
