1. Year 9 CHEMISTRY

2. Group 1- Alkali metals Highly reactive
Low melting points and boiling points
Light
Soft
E.g. Cs

3. Group 2- Alkaline earth metals
Very reactive (but less than Alkali metals)
Light
Soft
(but stronger and denser than Alkali metals)
E.g Mg

4. Transition metals
Less reactive than Alkali and Alkaline earth metals but vary in reactivity.
E.g. Au

5. Group 7- Halogens
Can be extremely dangerous.
Very reactive non-metals

6. Group 8- Noble gases Relatively non-reactive Low boiling points
Gases at room temperature

7. Questions What group has the most reactive metals?
What group has the most reactive non-metals?
Which group is nonreactive?
