Group 7 metals - Halogens

• Group 7 metal are called halogens
• Group 7 metals:

  1. Flourine (F) - Pale yellow gas
  2. Chlorine (Cl) - Yellowish Green Gas
  3. Bromine (Br) - Red-Brown Liquid
  4. Iodine (I) - Purple Solid
• Going down the periodic table the size of atom increases (there are more shells)
• By going down the group the reactivity decreases
• Halogens are non-metal
• Called group 7 because they have 7 electron in the outter most shell
• going down the boiling point and melting point increases
