PERIODIC TABLE
- Group ONE
  - Facts
    - After reaction it has a positive charge
    - Has one electron on outer shell until reaction
    - They are all Alkali
  - Reason Why
    - It is easier,and quicker for one to be lost so it reacts more. But the reason that lithium is less reactive, is because it has less electrons, so the connection is stronger.
  - Examples
    - Li
      - Na
        K
        Rb
        Cs
        Fr
- Group SEVEN
  - Facts
    - It always has seven electrons on the outer shell
    - After reaction it always has a negative charge
    - Theyare all non-metals
  - Examples
    - Florine
      - Chorine
        Bromine
        Idine
        Astotine
  - Reason Why
    - It wants to take an electron to complete its outer shell to become stable, rather tan lose 7 electrons.
    - The ones with less electrons are more reactive as they have a stronger pulling force than ones with lots of electrons.
    - It will have a negative charge as it will have more electrons than protons.
- Group ZERO
  - Facts
    - They all have full outer shell of electrons (8)
    - They are all stable
    - It will never react
    - They are all non-metals
  - Examples
    - He
      - Ne
        Ar
        Kr
        Xe
        Rn
  - Reason Why
    - It has no needs, it has every thing it needs to be stable so will not react because atoms only react to become stable.
