C1 - Atomic Structure & the Periodic Table

1. group 1

   • Lithium(Li) Sodium (Na) Potassium(K) Rubidium(Rb) Ceasium(Cs)
   • The Alkili Metals
     • reaction with water
       • sodium
         • fizzed , melted yellow-orange
       • lithium
         • fizzed,crimson red flame
       • potassium
         • fizzed , caught fire , exploded lilac flame
     • stored in oil because they react with oxygen and water very quickly
   • The reactivity increases as you go down the group

2. group 7

   • group 0
     • very unreactive because they have full outer shell of electrons
     • density increases as you go down the group
     • size of atom decreases as you go up the group
   • the halogens
     • flourine
       • chlorine
         • bromine
           • iodine
     • the reactivity decreases as you go down the group

3. non-metals

   • metals to the left of the stair line and the non metals to the right
