Question

Why did rutherford suggest that the positive charge in an atomic nucleus is concentrated in a tiny region rather than spread evenly throughout the atom?

Answer 1

Technically he tried shooting particles through a thin foil and looked at the results through an electronic microscope and found that the particles he shot that went through the sheet all passed through the side of the atoms and the ones that hit the center bounced off. This is because the particles he used are positively charged and the nucleus of the atom is positively charged, positive and positive repels and thus the particles bounce off and concluded that the denser part of the atom (nucleus) is positive and filled worth protons.

Hope that helped. Cheers =D

Answer 2

Rutherford showed that the atomic nucleus was positively charged because the alpha particles that he fired at the metal foils were positively charged, and like charges repel. . In Rutherford's experiments, the alpha particles moved through the foil without being deflected and sometimes it did deflect on their way. The alpha particles rarely deflected at a 180 degree angle. Since like charges repel, Rutherford had come to a conclusion that the cause of the deflections of the alpha particles must be some positive charge which is present in the atom.

What is atomic nucleus?

Atomic nucleus is "the central area of the atom. It is composed of two kinds of subatomic particles: protons and neutrons".

What is alpha particles?

Alpha particle is "a positively charged particle, identical to the nucleus of the helium-4 atom".
