Structure of Atom
Why do fireworks glow in different colours, and why does each element give a unique fingerprint of light. This chapter in NCERT Class 11 Chemistry, Chapter 2, traces discovery of electron, proton and neutron, Thomson and Rutherford models, Bohr theory, line spectra and the limits of classical ideas. It introduces dual behaviour of matter, Heisenberg principle, quantum numbers, orbital shapes and rules for filling electrons. You will learn to write electronic configurations and to link atomic structure with position in the periodic table.
