Physical Trends of Group 7

Physical Trends of Group 7

Group 7 Trends Summary

The halogens exist as simple covalent diatomic molecules (F2\text{F}_2F2​, Cl2\text{Cl}_2Cl2​, Br2\text{Br}_2Br2​, I2\text{I}_2I2​). As you move down the group, their boiling points increase while their electronegativities decrease.

Step-by-step lessons on AQA A Level Chemistry Trends in properties. Each one builds up to exam-style questions. Build confidence with atomic structure, bonding and moles calculations early on, since these underpin the more demanding organic mechanisms, equilibrium and practical-analysis topics that dominate Year 2.
