2. Structure of Atom
The chapter outlines the structure of atoms, beginning with historical atomic theories and moving on to the discovery of sub-atomic particles including electrons, protons, and neutrons. It discusses various atomic models, particularly Bohr's model, and introduces the quantum mechanical model to explain electron behavior by incorporating duality and probability principles. Finally, it delves into the organization of electronic configurations based on defined quantum numbers.

What we have learnt
- Atoms are the fundamental building blocks of matter consisting of electrons, protons, and neutrons.
- Bohr's model accurately predicts hydrogen atom spectra but fails to account for multi-electron atoms.
- The Schrödinger equation provides a quantum mechanical framework, allowing for predictions of electron distributions and energies.
Key Concepts
- -- Atom
- The basic unit of a chemical element, made up of protons, neutrons, and electrons.
- -- Subatomic Particles
- Particles that are smaller than an atom, which include electrons, protons, and neutrons.
- -- Quantum Mechanical Model
- A model of atomic structure that incorporates quantum mechanics, describing electrons as wave functions instead of fixed orbits.
- -- Quantum Numbers
- A set of numbers used to describe the unique quantum state of an electron in an atom.
