Periodic Trends in Chemistry
Unknown Grade•45 minutes
Learning Objective
I can explain how periodic trends such as electronegativity and atomic radius vary across the periodic table.
Practice Questions
This lesson includes 7 practice questions to reinforce learning.
View questions preview
1. Define atomic radius and explain how it changes as you move down a group and across a period in the periodic table.
2. Describe the relationship between ionization energy and atomic radius. How does this relationship manifest as you move across a period?
3. Explain the concept of electronegativity and discuss how it varies across the periodic table. Why does fluorine have the highest electronegativity?
