- - - - Alkali metals
        
        Group 1
      - halogens
        
        Group 17
      - Noble gases
        
        Group 18
      - transition metals
        
        Group 3 - 12 except Lanthanum, Actinium,
    - - alkali metals
        
        Atomic radius / reactivity increases down a group
      - halogens
        
        Atomic radius increases down a group while reactivity decreases. (increases going up)
- - - - Postive charge
      - mass = 1
    - - no charge
      - mass = 1
    - - negative charge
      - mass = 0
- - - - substance made up of 2 or more different element. (can be broken down by chemical reaction)
    - - substance made up of 2 or more different elements
    - - the basic unit of all element.
    - - substance made up of 2 or more element or elements and compound or multiple compounds NOT combined together. Still have the properties of what it is made of. (could be separated by physical process)
