Edexcel A level chemistry help!!

Can someone please explain why group 2 elements have a higher melting point than group 1 elements?? Does it have anything to do with increase in nuclear charge or is it something to do with London forces? Very confused 😰
Think about what group 2 elements are and their bonding. Hint: magnesium is a group 2 element.

Ohhh hold on - metallic bonding right?? So there will be a stronger attraction to the delocalised electrons in the metallic bonding lattice?

Has as Group 2 has 2+ ions and Group 1 has 1+ ions so group 2 has stronger metallic bonds

Yeah there’s stronger attraction as the ions are 2+ instead of 1+ and there’s more delocalised electrons (2 per atom instead of 1).

Ok that makes so much more sense and now I understand better - thank you for your help! 😊
