Atoms 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, quantum numbers. We will also learn the rules for writing the electronic configurations of atoms.
