Group 2 and Group 2 Trends

HideShow resource information

Ionisation Energy Decreases Down The Group

Each element has 1 extra electron shell as you go down, so therefore there is alot of shielding that happens. This then results in a lower ionisation energy.

Group 2 Reacts With Water,Oxygen and Chlorine

Water forms HYDROXIDES

Oxygen forms CHARACTERISTIC FLAME COLOURS

Chlorine forms solid CHLORIDES

The oxides and hydroxides are BASES, and therefore form alkali solutions and neutralise acids.

Solubility Trends are Complicated 

Single charged ANIONS (OH-)

Means solubility increases as you go DOWN the group

Double charged ANIONS (SO4 2-)

Means solubility increases as you go UP the group

Thermal Stability

- ANIONS…
