A student of Niels Bohr did not discover neutrons; Rutherford's student, James Chadwick, did.
Neils Bohr changed the current view of the atom by adding a nucleus with made up of protons and neutrons.
He suggested that electrons must be orbiting the nucleus in a certain fixed energy level or shells He also thought that each electron has it's own level of energy, and rotates the Nucleus -- Jopika
The short answer is that Ernest Rutherford discovered the nucleus of the atom and was a mentor to Niels Bohr who further refined the model by showing that the nucleus was made up of neutrons and protons. The existence of electrons had already been inferred earlier. Ernest Rutherford opened the door to the field of nuclear physics whereas Niels Bohr's contributions pointed the way to quantum physics. At the time, it was noted that the nucleus within the atom takes up about as much space as a fly in a cathedral. Since then, it has been shown that the subatomic particles are themselves made up mostly of vast empty spaces containing tiny specs of something that may be described as either energy or matter or neither and both.
He discovered this in 1764
Niels Bohr published his atomic theory in 1913...which applied Max Planck's quantum theory to Rutherford's idea of a nuclear structure.... adding the idea of electrons traveling in orbitsaround the atom's nucleus.

Niels Bohr
1914-discovered that electrons(negatively charged subatomic particles) orbit the nucleus(containing positively charged protons and neutrally charged neutrons) in specific energy levels
Neils Bohr changed the current view of the atom by adding a nucleus with made up of protons and neutrons.
a Bohr model is a diagram of an atom that describes the arrangement of the subatomic particles(electrons, neutrons, and protons) protons and neutrons are in the nucleus and the electrons in the electron shells.
Niels Bohr placed in the center of atom the atomic nucleus and electrons in movement around nucleus.
give the compound nucleus hypothesis
The scientist who discovered that atoms have an energy level is Niels Bohr in 1913. According to his model electrons move around the nucleus much the same as the planets rotate around the sun.

Niels Borh, a Danish scientist, discovered this in 1913
