✋Introduction
Group 7 (halogens)
In this lesson: I can describe the pattern in reactivity of Group 7 non-metals and name the products of reactions between metals and halogens. The elements in Group 7 are all non-metals that have coloured vapours, most of which are toxic. The state of the elements at room temperature changes from gas to solid, down Group 7.
