9th Chemistry Chapter3 Periodic Table and Periodicity of Properties

1. How are elements arranged in a period, and what trends can be observed across a period?
Explain the concept of periodicity in the periodic table.

2. Discuss the trend in electron affinity as you move across a period in the periodic table.
Explain the concept of atomic radius and how it varies across the periodic table.

3. How does the periodic trend in electronegativity contribute to the nature of chemical bonds?
Discuss the periodic trend in the atomic radii of transition metals.

4. Explain the trend in ionization energy across a period and down a group.
Explain the concept of electron shielding and its impact on periodic trends.
