Group 7 - Halogens
Color (As darker as you go down the group)
Chlorine - Yellow- green
Bromine - Red - Brown
Fluorine - Yellow
Iodine - Shiny purple
Reactivity (Get less as go down the group)
Fluorine - Almost reacts with everything
Chlorine - Reacts with heated iron wool very quickly
Bromine - Has to be warmed and heated with iron wool
Iodine - Has to be heated strongly and reaction is slow
Properties of Halogen
Iodine - Grey Solid - Sterilizing the wounds
Bromine - Orange Liquid - Pesticides or Plastics
Chlorine - Green gas - Sterilizing the water
Room temperature 25*C
Bromine - Liquid
Iodine, Astatine - Solid
Fluorine, Chlorine- Gas
Density
As mass and volume are increasing as we go down a group,
So density is also increasing as an order.
