ATOMS AND ELEMENTS - Coggle Diagram

- - - - non-metals
        
        each one has a different colour
        
        some of them kill bacteria and libing organisms in water
    - - none of them is chemically reactive
        
        the density of them increases steadily
    - - color: silver-grey
        
        malleable and ductile
        
        low melting points
        
        react with water and air
        
        soft
- - - - Lose or gain electrons.
      - Example: NaCl
    - - Share electrons.
      - Example: hydrogen - water
- - - - Beta-Minus Decay
        
        Energetic negative electron is emitted, producing another nucleus.
        
        one higher atomic mass
        
        same mass number
      - Gamma Decay
        
        Accompanies alpha or beta decay.
      - Alpha Decay
        
        Energetic helium ion is ejected, leaving another smaller.
        
        atomic number two less than the other
        
        atomic mass number four less than the other.
