Building Blocks (Atoms (Simplest whole unit of an element (Element (A…

- - - - A substance made up of only one type of Atom #
  - - - Like a cake after being baked.
  - - - Like a cake mixture
- - - - E.g. Turing ice into water.
        
        Melting point
        
        The temperature when you can melt
        a solid into a liquid .
        
        Boiling point
        
        The temperature when you can heat a liquid onto a gas.
  - - - E.g. boiling an egg.
- - - - The gain of oxygen from a substance.
  - - - H
      - Element
- - - - Solid at room temperature (not mercury)
        
        Good at conducting heat
        (Look at Energy transfer more detail)
        
        Good conductors of electricity
        
        Called ductile
        
        Iron, colbat, nicklet and their mixtures are magnetic
    - - Strong strength
        
        Malleable
        
        Rings like a bell when hit
        
        Called sonorous
        
        The property of metals were they can be crushed into shape.
  - - - About half are solid, about half are gasses and one is liquid (bromine) at room temperature .
      - Not as dense as metals
        
        Weak
        
        Brittle
        
        Meaning they break or shatter
        when hit
        
        Bad conductors of heat.
      - Bad conductors of electricity
        
        Meaning they are insulators apart
        from graphite.
        
        Not magnetic
        
        Makes a dull sound when hit .
- - - - Put your testing substance in some hydronic acid and
        attach a straw into it using a rubber bung.
        
        Put that tube/straw into another test tube contains lime water.
        
        If lime water turns cloudy it means your substance contains
        carbon dioxide.
    - - Put testing substance into a test tube with
        some hydronic acid. Quickly add another tests tube on top.
        
        After a while put the bottom test tube away.
        
        Put a lighted wooden splint in th stop tube
        and if it makes a pop your substances has hydrogen .
    - - Put testing substance into a test tube with
        some hydronic acid. Quickly add another tests tube on top. #
        
        Put a glowing splint into the top tube and if the splint
        reignites it means your substance has oxygen.
