Chemistry Unit 2 AQA Halogen and Halides

Halogen and Halides

• The halogens are in group 7, the halides are the ions that the halogens form
• The halogens make salts.
• From Flourine to Iodine the boiling points increase, this is due to there being more electrons for iodine therefore stronger intermolecular forces are formed. These stronger Van der Waals forces require more energy to be broken, hence the higher boiling point.
• From Iodine to Flourine the electronegativity increases because flourine has the least shielding from the sub shells and it has the smallest atomic…
