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

Frequently asked questions

How long should a Atomic Structure mock test take?

For a topic-level test, aim for 20–30 minutes. For a full subject mock, allow 60–90 minutes to mirror JEE timing.

What is a good score on a Atomic Structure mock test?

Aim for 70%+ accuracy initially, then push toward 85%+ as your exam date approaches. Review explanations for every wrong answer.

Does Goodmarks score mock tests automatically?

Yes. Each MCQ is scored instantly with the correct answer and explanation shown after submission.

Can I retake the same mock test?

Pro users can generate new question sets by topic. Reattempting the same questions after a gap is excellent for retention.
