1. Why is Mg (carbonate and nitrate) the least thermally stable of the G2 elements ?

  • Magnesium isn't the least thermally stable, Barium is.
  • Magnesium has the smallest ionic radius as a 2+ cation so a greater polarising ability (more charge dense)
  • Magnesium has the largest nuclear charge so can most easily pull apart the electron cloud
  • Magnesium forms radioactive carbonates and nitrates that are unstable and break down

4. What is the trend in ionisation energy down group 2?

  • It decreases due to the replusion and number of quantum shells increasing
  • It increases up to Calcium then drops sharply
  • It increases due to the increased nuclear charge
  • It decreases due to the size of the metallic radius decreasing
