A Level Chemistry

General trends of Group 2 elements

Atomic radius – increases down the group.  TIB – more shells, more shielding, less attraction from nucleus to outer electrons

First ionisation energy – decreases down the group TIB – more shells, more shielding, less attraction from nucleus to outer electrons

Melting points – decrease down the group.  TIB – attraction between smaller cations and delocalised electrons will be stronger
