Group 2

• Group 2 metals react with water to give metal hydroxides and hydrogen gas
• Group 2 metals burn in oxygen to form solid white oxides
• Trend in reactivity with water

  Increases down group
• Trend in pH of hydroxides in water

  Increasing pH down group
• Trend in solubility of hydroxides

  Increases down group
• Trend in solubility of carbonates

  Increasing solubility up the group
• Trend in thermal stability

  Thermal stability increases down the group
