The nuclear atom model put forward by Ernest Rutherfort is Rutherford's model on a thin gold plate. It is based on the observation of the scattering behavior of the transmitted alpha particles. Accordingly, given which one is wrong?      a)  The positively charged protons inside the atom are concentrated in the nucleus.  B) Most of the alpha particles are backscattered after hitting the gold plate.  NS)  Few of the positively charged alpha particles hit the gold plate and are scattered back at a large angle.  D)  Most of the positively charged alpha particles passed through the gold plate without any scattering.  TO) The nucleus, where the protons are together, occupies a very small volume.

Rutherford's scattering experiment

Rutherford’s scattering experiment is also known as the gold foil experiment. This experiment disproved the plum pudding model of J.J. Thomson. In a gold foil experiment, high-energy alpha particles are made to strike a thin gold foil. The scattered alpha particles are detected using a detector. This experiment showed that the positive charge of the atom is at the center. Most of the atom’s mass is also confined to a small volume at the center. This region is known as the nucleus of the atom.
