General Trends Across a Period
Students will identify general trends in physical and chemical properties across a period, focusing on the change from metallic to non-metallic character.
Key Questions
- Describe the general trend in metallic and non-metallic character across a period.
- Explain how the number of valence electrons changes across a period.
- Predict the general reactivity of elements based on their position in a period.
