GCSE Chemistry - Group 7 & Group 0 Elements - Halogens & Noble Gases | Properties | Trends

⭐️ Check out our website https://www.cognito.org/ ⭐️ ** WHAT'S COVERED ** 1. Group 7 - The Halogens Physical properties and states of fluorine, chlorine, bromine, and iodine. How halogens exist as diatomic molecules by forming covalent bonds. Formation of simple molecular structures with other non-metals. 2. Trends in Group 7 Melting and boiling points increase down the group. Reactivity decreases down the group, with an explanation of the underlying atomic structure. 3. Halogen Reactions Formation of halide ions and ionic bonds with metals. Displacement reactions, where a more reactive halogen displaces a less reactive one from a solution of its salt. 4. Group 0 - The Noble Gases Properties of noble gases, including being inert, colourless, and non-flammable due to their full outer shell of electrons. The trend of increasing boiling points as you go down the group. ** CHAPTERS ** 0:00 Introduction 0:23 Properties of the Halogens 1:05 Covalent Bonding in Halogens 1:50 Trends in the Halogens 2:37 Halide Ions & Ionic Bonding 3:18 Displacement Reactions 4:07 Properties of the Noble Gases 4:38 Trends in the Noble Gases ** PLAYLISTS **    • KS3 Biology      • KS3 Chemistry      • GCSE Maths (9-1)      • GCSE Biology (9-1)      • GCSE Chemistry (9-1)      • GCSE Physics (9-1)      • A-Level Biology   #GCSE #Chemistry #study #revision #school #exam #AQA #OCR #Edexcel #IGCSE
