Question

Find the number of electrons, protons and neutrons possessed by the alpha particles (4/2 He++) used in the gold leaf experiment,

Answer 1

Here is the answer for your question

Answer 2

Alpha Particles

Explanation:

Ernest Rutherford observed the scattering of alpha particles when they were shot through a thin gold foil. Alpha particles are the nuclei of helium atoms. They have two neutrons and two protons. It does not have no electrons to balance the protons, hence they are positively charged. Alpha particles possess high mass and electrical charge, so they are unable to penetrate as deep as other particles such as protons and electrons. But, due to their positive charge, alpha particles will interact very strongly with the atoms of the gold foil in this experiment.
