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

Periodic Trends:
- The periodic table is a fundamental tool in chemistry that organizes elements based on their atomic numbers and chemical properties.
- Periodic trends refer to the patterns that emerge when certain properties of elements change as you move across a period or down a group in the periodic table.
- These trends include atomic radius, ionization energy, electron affinity, electronegativity, and metallic character.
- Questions related to periodic trends may involve predicting the trend for a given property based on the element's position in the periodic table or explaining why certain trends occur.

Properties of Elements:
- The properties of elements depend on their atomic structure, including the number of protons, neutrons, and electrons.
- Questions may involve the identification of elements based on their properties or predicting the properties of elements based on their position in the periodic table.
- Some important properties include the reactivity of elements, their ability to form compounds, physical properties such as boiling point and melting point, and their behavior in different chemical reactions.

Examples of Questions:
1. Which element is expected to have a larger atomic radius: oxygen or sulfur?
2. Arrange the elements nitrogen, phosphorus, and arsenic in order of increasing electronegativity.
3. Predict the most likely charge on a calcium ion.
4. Which element is expected to have a higher ionization energy: sodium or potassium?
5. Identify the element with the highest electron affinity: chlorine, bromine, or iodine.

Preparation Tips:
- Familiarize yourself with the periodic table and understand how elements are organized.
- Study the trends in atomic radius, ionization energy, electron affinity, electronegativity, and metallic character.
- Practice solving questions that involve predicting trends and explaining the reasoning behind them.
- Review the properties of different elements and understand how they relate to their atomic structures.
- Solve previous years' question papers and take mock tests to assess your understanding and time management skills.

Conclusion:
The JEE Advanced exam may include questions related to periodic trends and properties of elements in the chemistry section. It is important to understand the organization of the periodic table, the trends in various properties, and the relationship between atomic structure and element properties. Practice solving questions and familiarize yourself with the types of questions that may be asked in order to prepare effectively for this topic.
