metals/non metals

• when metals react they lose electrons to acheive a full outer shell
• metals always form positive ions
• non metals either

  -dont form ions

  -form negative ions
• all metals have metallic bonding which os very strong and responsible for the physical properties
• metals are malleable meaning they can be bent or hammered into different shapes
• metals are great at conducting heat and electricity
• metals have high boiling and melting point
• non metals tend to be dull, brittle, arent always solids at room temperature, dont generally conduct electricity and often have lower density
• catalysts are substances which increase the rate of a chemical reaction without being used up themselves
• transition metals make very good catalysts
