Question

Niels Bohr used quantum mechanics to describe which element?​

Answer 1

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.

Answer 2

Niels Bohr used quantum mechanics to describe Hydrogen element .
