Group 7 - The Halogens

Group 7 - The Halogens

• Non-metals like fluorine, chlorine, bromine, iodine are very reactive and form diatomic molecules.
• The oxidising ability of halogens decreases down the group.
• Higher halogens displacing lower halogen in aqueous salts is a trend.
• Practice includes explaining trends in electronegativity, boiling points, and halogens’ oxidising ability.
