Check what you remember
Read the wording for your board, then hide it and explain increasing reactivity down the group in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
Calcium, strontium and barium all react with cold water directly and with increasing vigour, as the ionisation energies fall.
