Reactivity Series & Displacement Reactions

• Metals that loose electrons easily are the most reactive.

  
• Group 1 Metals are the most reactive and they only need to loose 1 electron in their outer shell.

  
• Transition Metals are not very reactive.
• Metal + Acid -> Salt + Hydrogen gas

  
• Metal + Water -> Metal Hydroxide + Hydrogen gas

  
• Displacement: Where a more reactive metal replaces a less reactive metal.

  
• You can measure temperature change as Most reactive metals produce the most heat.
• Potassium is the most reactive, Sodium and Lithum. Are very violent, move vigourously and may explode. Anything below may bubble.

  
• Group 7 (Halogens) Get less reactive going down. But have HIGHER melting and boiling points.
