The reason for decrease in the chemical reactivity of elements of group 7A from top to bottom should be explained. Concept introduction: The group 7A elements show variation from non-metals to metals down in the group. The first element of the group 7A is fluorine with 7 valence electrons. The group 7A is a good combination of non-metals with only at as radioactive element. The first element of the group 7A is fluorine with 7 valence electrons. The elements of 7A exhibit the variation in the physical state from gas to liquid then to solid.
