large anion
affected more by smaller and
highly charged cation
beryllium is the least thermally stable as it has a high charge and a small radius
caesium
is the most thermally stable as it has a
low
charge and a large radius
metal
nitrate
= metal nitrite +
oxygen
metal nitrate = metal oxide +
nitrogen
dioxide +
oxygen
the best decomposition is when there is a small high charged cation and a large high charged anion
hydroxides
thermal stability
the thermal stability decreases down the group
solubility
of
hydroxides
increases down the group
thermal stability
of
carbonates
increases as you go down the
group
solubility
of
sulphates
decreases down the group
thermal stability
of
sulphates
decreases down the group
