Metals + Non metals

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

  This creates ions with a positive charge. 
• Fluorine atoms have 7 electrons in their outer shell. In chemical reactions, do they gain or lose electron(s)?

  Gain
• 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
