According to Rutherford's model of the atom



According to Rutherford’s model of the atom, where is the positive charge concentrated? What does it predict about the relative size of the nucleus and the radius of the atom? What is the nucleus composed of according to his model?


According to Rutherford’s model of atom, the positive charge is concentrated at the centre, that is, at the nucleus.Since a small fraction of ∝-particles were deflected through small angle and also a few of them bounced back, it proved that the nucleus occupies a very small volume in the atom. The radius of the atom is about ${{10}^{-10}}$m while of nucleus is ${{10}^{-15}}$ m. The nucleus is composed of protons and neutrons and is surrounded by revolving electrons.
