2. Neils Bohr​

Answer 1

In 1932, Chadwick made a fundamental discovery in the domain of nuclear science: he proved the existence of neutrons – elementary particles devoid of any electrical charge..

In .1913, Niels Bohr proposed a theory for the hydrogen atom based on quantum theory that energy is transferred only in certain well defined quantities. Electrons should move around the nucleus but only in prescribed orbits. When jumping from one orbit to another with lower energy, a light quantum is emitted.

Answer 2

Answer:

● James Chadwick discovered Neutron.

● Neil Bohr proposed theory for Hydrogen atom.
