How did Sir James Chadwick discover the neutron?
In 1932, the physicist James Chadwick conducted an experiment in which he bombarded Beryllium with alpha particles from the natural radioactive decay of Polonium. The resulting radiation showed high penetration through a lead shield, which could not be explained via the particles known at that time.
Who discovered proton Class 9?
The discovery of the proton is credited to Ernest Rutherford, who proved that the nucleus of the hydrogen atom (i.e. a proton) is present in the nuclei of all other atoms in the year 1917.

What was the name of James Chadwick’s atomic model?
Chadwick’s discovery forced a revision of the cloud model, and scientists sometimes refer to the revised version as the James Chadwick atomic model. Read everything about it here. Herein, what is the current atomic model called? The modern model is also commonly called the electron cloud model.
What was the name of James Chadwick’s experiment?
What was the name of James Chadwick’s model? Chadwick is responsible for discovering the existence of the neutron, the neutral particle that shares the nucleus with the positively charged proton. Chadwick’s discovery forced a revision of the cloud model, and scientists sometimes refer to the revised version as the James Chadwick atomic model.
