CI : atomic structure and PT - metals and non metals

• Metals and Nonmetals
• Most elements are metals
• Metals are elements which can form positive ions when they react
• Metals are on the left and non metals are on the right
• Non metals do'nt usually form positive ions
• The Electronic structure of the atoms affect how they react with each other
• Atoms are more stable with a full outer shell , they react by losing , gaining or sharing electrons
• Metal elements are on the left towards the bottom so they lose electrons easily. when this happens they form positive ions , with a full outer shell .
• Non-metals are towards the right so its easier to share or gain electrons
• Metals and Non-metals have different physical properties
• Metals : =
• • They are stronger and can be bent into different shapes
  • They are good at conducting heat and electricity
  • They have a high boiling and melting point
• Non-metals :
• • They are more dull looking
  • They are more brittle . ( this means they can break more easily )
  • They are not always solid at room temperature
  • They do not conduct electricity
  • They are lower in density
