metals and non-metals

• When metal atoms react, they lose electron(s) from their outer shell. 

  This creates ions with a positive charge
• general properties of metals:

  • Good conductors of heat 
  • Malleable
  • Sonorous (produce a ringing sound when struck)
• Metals are very strong, as the ions are held together by metallic bonds. 

  They also tend to be malleable, which means they can bend without breaking. 

  Non-metals, in contrast, break easily, and so are said to be brittle
