2. What are Halogens?
Halogens are elements that are found in the VIIth group of the periodic table
Since they are in group VII they all have a Valency of -1

3. Elements The elements in the group are : Fluorine- F9 -2,7
Chlorine- Cl17 -2,8,7
Bromine- B35 -2,8,18,7
Iodine- I53 – 2,8,18,8,8,8,1
Astatine- At85 – 2,8,18,32,8,8,8,1

5. State of Matter
Halogens can be found in the form of all three states of matter-solids, liquids, gas
Fluorine and chlorine are found in the gas form
Iodine and astatine are found in the solid form
Bromine is found in the liquid form

6. Iron + bromine iron (III) bromide. 2Fe(s) + 3Br2 (l) 2FeBr3(s)
Reaction with metals
When Halogens react with metals they form the metal salt
Halogen literally means salt former
Iron + bromine         iron (III) bromide. 2Fe(s) +    3Br2 (l)              2FeBr3(s)
These then form large structures known as metal halides
