- The Periodic Table- GROUP ONE
- moving DOWN the group..
- the metals become MORE REACTIVE
- the outer electron is easily lost
- it is further away from the nucleus
- the outer electron is easily lost
- the metals have LOWER melting and boiling points
- the metals become MORE REACTIVE
- they are all ALKALI METALS
- low densities
- all have 1 outer electron
- makes them more reactive and gives them similar properties
- all have 1 outer electron
- LITHIUM
- SODIUM
- POTASSIUM
- RUBIDIUM
- CAESIUM
- low densities
- the alkali metals form IONIC COMPOUNDS WITH NON- METALS
- want to lose their outer electron
- to form a 1+ ion
- no way they'd consider sharing
- covalent bonding= X
- they form IONIC BONDS
- these produce white compounds that dissolve in water to form colourless solutions
- want to lose their outer electron
- REACTION WITH WATER PRODUCES HYDROGEN GAS
- vigorous reactions
- float and move around the surface, fizzing furiously
- Lithium, Sodium or Potassium
- vigorous reactions
- float and move around the surface, fizzing furiously
- vigorous reactions
- Untitled
- produce hydrogen
- potassium gets hot enough to ignite it
- a lighted splint will indicate hydrogen by making a sqeaky pop as the H2 ignites
- potassium gets hot enough to ignite it
- they form HYDROXIDES that dissolve in water to give ALKALINE SOLUTIONS
- vigorous reactions
- moving DOWN the group..
