- The Group 7 Elements
- At room temperature, chlorine is a green gas, bromine is an orange liquid and iodine is a grey solid
- The group 7 elements have similar properties because they have 7 electrons on the outer shell
- When halogens react with alkali metals, a metal halide is made
- Potassium+ iodine ---> potassium iodide
- The reactivity of halogens increases further up the group
- If electrons are gained, the process is called reduction
- Br2 + 2e- --->2Br-
