The periodic table - Coggle Diagram

- - - - Example: copper and nickel don't react with water, but sodium yes.
    - - Group 1 metals, always 1+ on change on ions. Example: sodium.
      - Transition elements, variable on charge of ions. Example: copper.
      - Group 3 metals, always 3+. Example: aluminium.
- - - - it forms colored gasses , fluorine is pale yellow gas and chlorine is a green gas. Brommie forms a red vapor, and iodine a purple vapor. These are poisonous
    - - halogen:Fluorine, reaction with iron wool :iron wool bursts into flame as fluorine passes over it without any heating .the product --> iron fluoride . product--> iron chloride,FeF3, yellow solid.
      - halogen:Chlorine , reaction with iron wool--> iron wool burst into flame as fluorine passes over it without heating. product--> iron fluoride FeCl3, yellow solid.
      - Halogen:Bromie, reaction with iron wool : hot iron wool glows when roomie vapor passes through it. product--> iron bromide, Fe Br3, red-brown solid
      - halogen: iodine, reaction with iron wool: hot iron wool shows faint red glow when iodine vapor passes over it. product--> iron iodide, fel3.black solid.
    - - Halogen: fluorine : at room temp a yellow gas . Boiling point: -188
      - Halogen chlorine: a green gas . Boiling point -135
      - iodine: a black liquid. Boiling point 184
      - brommie : a red liquid . boiling point :59
  - - - Physical properties
        
        softer, lighter and less denser than other metals
        
        have low melting and boiling points.
        
        Like all metals, good conductors of electricity
      - Chemical properties
        
        reaction with chlorine
        
        If you heat the 3 materails, and plunge them into gas jars of chlorine, they burst into the flame. they burn slowly and forms chlorides. Example: sodium+ chlorine=sodium chloride.
        
        reaction with oxygen
        
        The 3 metals also burst into flame when you heat them and plungr them into gas jars with oxygen. They burn fiercely to form oxides. Thsese dissolves in water to give alkaline solutions.
        
        reaction with water
        
        Alkali metals react vigorously with water. Hydrogen bubbles off, leaving solutions of their hysroxides, wich are alkalis.
  - - - The noble gases are unreactive because their atoms have already stable outer electron shell.
    - - helium: a balloon full of gas rises quickly because it is less denser,
      - neon is more denser than helium
      - argon is more denser than neon and so on...
    - - helium: balloons
      - argon: to provide an inert atmosphere .
      - Krypton is used in lasers for surgery.
