Yes, you can expect questions from atomic structure and periodic properties in the chemistry section of the JEE Advanced exam.

Atomic Structure:
- This topic focuses on the structure of atoms, including the arrangement of subatomic particles such as protons, neutrons, and electrons.
- Questions may test your understanding of concepts such as atomic number, mass number, electronic configuration, and the distribution of electrons in different orbitals.
- You may be asked to determine the number of valence electrons or the electronic configuration of an element.
- Questions may also involve calculations related to atomic structure, such as determining the average atomic mass or the energy of an electron in a particular orbital.

Periodic Properties:
- Periodic properties refer to the trends and patterns observed in the properties of elements as they are arranged in the periodic table.
- Questions may test your knowledge of periodic trends such as atomic radius, ionization energy, electron affinity, and electronegativity.
- You may be asked to identify the element with the highest or lowest value of a particular property.
- Questions may also require you to predict the properties of an element based on its position in the periodic table.
- You may need to analyze and interpret data from the periodic table to answer questions related to periodic properties.
