Niels Bohr assumed that the angular momentum of the electron in the hydrogen atom can have only certain discrete values, which he called "quantized" values. This assumption was one of the key features of his model, as it explained why the electrons do not spiral into the nucleus and why the observed spectral lines of hydrogen were discrete and not continuous.
