WebAtoms are the foundation of chemistry. They are the basis for everything in the Universe. In this second unit of class 11 chemistry, we will learn the discovery of subatomic particles- electrons, neutrons, & protons, atomic models of J.J Thomson's, Rutherford's, Bohr's. We will learn the dual nature of light and electron, quantum mechanics ... WebNuclear Model Of The Atom. Based on his observations and conclusions, Rutherford proposed his model of the structure of the atom. According to this model –. Most of the mass of the atom and the positive charge is densely concentrated in a very small region in the atom. Rutherford called this region the nucleus.
