Work

The discovery of the electron and radioactivity in the late 19th century led to different models being proposed for the atom’s structure. In 1913, Niels Bohr proposed a theory for the hydrogen atom, based on quantum theory that some physical quantities only take discrete values. Electrons move around a nucleus, but only in prescribed orbits, and If electrons jump to a lower-energy orbit, the difference is sent out as radiation. Bohr’s model explained why atoms only emit light of fixed wavelengths, and later incorporated the theories on light quanta.
