- Properties of Group 2 metals include1234:
- Shiny, silvery-white appearance
- Relatively low densities
- Highly reactive, although not as reactive as the alkali metals in Group 1
- Readily lose two electrons to form +2 cations, resulting in stable electron configurations
- Low melting points and low densities
- Good conductors of heat and electricity
- General electronic configuration of ns 2
- Held together by metallic bonding
- As you go down group 2, atomic radius increases
- As you go down group 2, first ionisation energy decreases
- As you go down group 2, melting point (as a trend) decreases
- All elements in Group 2 have the two electrons in their outermost principal quantum shell
- All Group 2 metals can form ionic compounds in which they donate these two outermost electrons (so they act as reducing agents) to become an ion with +2 charge (so they themselves become oxidised)
- Going down the group, the metals become more reactive
