C3- Groups
- Group 1
- As you go DOWN, metals become MORE reactive, (outer electron is
more easily lost as it's further from nucleus)
- LOWER melting and boiling point as you go down
- LOW density
- Group 7
- As you go DOWN, it is LESS reactive, (it's harder to gain an extra electron
because outer shell is further from nucleus)
- HIGHER melting and boiling point as you go down
- Coloured vapours
- Transition elements
- Good conductors of heat and electricity
- Dense, strong (more than group 1) and shiny
- LESS reactive than group 1
- HIGHER melting and boiling points, (except Mercury)
- Compounds are very colourful and make good catalysts
