Group 7 elements are called the halogens. The term halogen means 'salt former'
4 main elements of the group7 (In order)
Chlorine
Bromine
Flourine
Iodine
Trends
The reactivity of the elements decrease as you go down the group. Fluorine is the most reactive of them all
The color of the elements become darker as you go down
the matter of state at room temperature for the elements as you go down is gas to liquid to solid
the density increases as you go down the group as the rate of increase for mass outpaces volume.
