  - - - Substances that's in a chemical reaction and undergoes a change
    - - A substance that's made at the end of a chemical reaction
    - - Pure substances never varies
      - NH3 is ammonia. Ammonia will always be NH3 and will never be anything else
    - - The mass of any element will have the same mass at the beginning or end
- - - - Divided into 3 subatomic particles
        
        Neutron
        
        A subatomic particle of without an electric charge
        
        Mass = 1 amu
        
        Placement = Inside the nucleus
        
        Electron
        
        a stable subatomic particle with a charge of negative electricity (-)
        
        Mass = Negligible (1/2000)
        
        Placement = Surrounds the nucleus with a shell
        
        Proton
        
        A stable subatomic particle occurring in all atomic nuclei, with a positive electric charge (+)
        
        Mass = 1 amu
        
        Placement = Inside the nucleus
  - - - A = Atomic mass (Proton + neutron)
        Z = Atomic number (Number of protons)
        Neutrons = (Mass number - protons)
