*** 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.
