Answer:
1913
Explanation:
A hypothesis of the hydrogen atom was developed by Niels Bohr in 1913, based on the quantum theory, which states that certain physical quantities can only have discrete values. Electronic particles travel about a nucleus, but only in specified orbits. If electrons jump to a lower-energy orbit, the energy difference between the two orbits is emitted as radiation.
Hope this helps explain what the answer to your question is and why it is that answer.
Answer:
1913
Explanation:
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.
