Physical Trends Down Group 2:
- 1. Atomic radius increases
- 2. First ionisation energy decreases
- 3. Melting point decreases - size of atom/ion increases so delocalised electrons are further from the nucleus therefore weaker electrostatic attraction between positive ions and delocalised electron (metallic bonding)
- Reactivity increases the more further the delocalised electron the easier the electrons are lost (vigorous reaction)
