Periodic Trends: Atomic Radius and Ionization Energy
Students will analyze how effective nuclear charge and shielding influence atomic radius and ionization energy across periods and groups.
Key Questions
- Explain why atomic radius generally decreases across a period despite an increase in the number of electrons.
- Predict how the first ionization energy will change for elements within the same group.
- Differentiate the factors that influence atomic radius from those that influence ionization energy.
