Yes, questions from atomic structure and electronic configuration can be expected in the physics section of the JEE Advanced exam.

Atomic Structure:
- The atomic structure is a fundamental topic in physics and is crucial for understanding the behavior of matter at the atomic level.
- Questions related to the Bohr model of the atom, quantization of energy levels, atomic spectra, and electron transitions may be asked.
- You may be required to calculate the energy levels, wavelengths, or frequencies associated with electron transitions.
- Questions on the wave-particle duality of electrons, Heisenberg's uncertainty principle, and the Schrödinger wave equation may also be included.

Electronic Configuration:
- Electronic configuration refers to the arrangement of electrons in different energy levels or orbitals of an atom.
- Questions may involve determining the electronic configuration of elements using the periodic table and understanding the rules governing electron filling.
- You may be asked to identify the valence electrons and their distribution in different shells.
- Questions on the Pauli exclusion principle, Hund's rule, and Aufbau principle may be included.
