Question

Which atomic model proposed that electrons move in specific orbits around the nucleus of an atom?

Answer 1

Bohr Atomic Model.  In 1913 Bohr proposed his quantized shell model of the atom to explain how electrons can have stable orbits around the nucleus.

Answer 2

Bohr's atomic model proposed that electrons move in specific orbits around the nucleus of an atom.Bohr proposed that electrons move in such orbit in which angular momentum of electron is integral multiple of 2π.In such orbit the electron does not absorb or emit energy.This orbits are called stationary orbit.the electron absorbs or emits energy when it jumps to another energy level.
