Check what you remember
Read the wording for your board, then hide it and explain metallic bonding and melting point in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
Melting point generally falls from calcium to barium because the larger 2⁺ ions sit further from the delocalised electrons and the metallic bonding weakens.
