Question

what is alpha particles experiment???​

Answer 1

Answer:

• The Alpha Particle Scattering Experiment. They took a thin gold foil having a thickness of 2.1×10-7 m and placed it in the centre of a rotatable detector made of zinc sulfide and a microscope. Then, they directed a beam of 5.5MeV alpha particles emitted from a radioactive source at the foil.

• Rutherford's alpha scattering experiment showed that the majority of alpha particles fired at a thin sheet of gold leaf passed straight through. Some of the particles passed through the leaf with a small angle of deflection and very few were deflected at very large angles.

Hope this helps you ☺️....

Answer 2

Thomson, proposed an experiment of scattering of alpha particles by atoms to understand the structure of an atom. ... In 1911, they performed the Alpha particle scattering experiment, which led to the birth of the 'nuclear model of an atom' – a major step towards how we see the atom today.
