   • group 1
     • liotheum (li)sodiem (na)potssiem(K)rubidium(RB)ceasiem(CS)
     • the alkali metals
       • stored in oil because they react with oxygen and water
       • reaction with water
         • lithium
           • fizzed crimson red flame
         • sodium
           • fizzed metal yellow and oringe flame
         • potassium
           • fizzed caught fire lilac flame
         • the recativity increases as you go down the group
   • group7
     • the halogens
       • florine
       • chlorine
       • bromine
       • iodine
   • group 0
     • the reactivity decreases as you go down the group
     • very unreactive because they have a full outer shell of electrons
     • density increases as you go down the group
     • the size of atomms increases as you go down the group
