- Group 1 - The Alkali Metals
- Stored in oil so they don't react with oxygen in air
- All have one electron on their outer shell so have similar properties.
- React vigorously with nonmetals.
- Reacts vigorously with chlorine and other halides to form a white compound.
- White metal compound is soluble in water and give colourless solutions.
- Reactions get more vigorous as you go down the group.
- Easier to lose single outer electron
- Reacts vigorously with chlorine and other halides to form a white compound.
- Softer than transition metals. Can be cut and shiny when cut.

- Group 1 - The Alkali Metals
- Soon become dull. Oxide layer forms on shiny surface as oxygen reacts.
- Softer than transition metals. Can be cut and shiny when cut.
- Softer than transition metals. Can be cut and shiny when cut.
- Less dense to transition elements.
- One electron on outermost shell so only need to lose one electron to get the structure of a noble gas.
- Form ionic bonds with a 1+ charge.
- Sodium, Lithium and Potassium all react with water to give an alkaline solution.
- Float on top and produce hydrogen gas.
- Potassium reacts with it so vigorously that the hydrogen catches fire, (lilac flame)
- Float on top and produce hydrogen gas.
