Subtopics in Atomic Structure

  • Nature of electromagnetic radiation, photoelectric effect, spectrum of the hydrogen atom
  • Bohr model of a hydrogen atom: its postulates, derivation of the relations for the energy of the electron and radii of the different orbits, limitations of Bohr's model
  • Dual nature of matter, de Broglie's relationship, Heisenberg uncertainty principle
  • Elementary ideas of quantum mechanics, the quantum mechanical model of the atom and its important features
  • Concept of atomic orbitals as one-electron wave functions, variation of Psi and Psi^2 with r for 1s and 2s orbitals
  • Various quantum numbers (principal, angular momentum and magnetic quantum numbers) and their significance
  • Shapes of s, p and d orbitals, electron spin and spin quantum number
  • Rules for filling electrons in orbitals: Aufbau principle, Pauli's exclusion principle and Hund's rule
  • Electronic configuration of elements and extra stability of half-filled and completely filled orbitals
