Question

Name the scientists who were responsible for the following scientific development:

The theory is that the electrons move in circular orbits around the nucleus of an atom.

Answer 1

1. The smallest unit of ordinary matter that makes up a chemical element is an atom.
2. Niels Bohr proposed a theory for the hydrogen atom in 1913, based on quantum theory, which states that some physical quantities have only discrete values.
3. Electrons circulate around a nucleus in predetermined orbits, and if they leap to a lower-energy orbit, the energy difference is radiated.

Hence, the theory that the electrons move in circular orbits around the nucleus of an atom was given by Niels Bohr.
