2. Why is Mg (carbonate and nitrate) the least thermally stable of the G2 elements ?
- Magnesium has the smallest ionic radius as a 2+ cation so a greater polarising ability (more charge dense)
- Magnesium isn't the least thermally stable, Barium is.
- Magnesium forms radioactive carbonates and nitrates that are unstable and break down
- Magnesium has the largest nuclear charge so can most easily pull apart the electron cloud
