1. ALKALI METALS
Locate the alkali metals (hint: they’re all in group 1) on your periodic table and colour them in using the coloured pencils at the front.
Extension: What is a property of the alkali metals?

2. LO:
Explain how electron configuration affects the reactivity of alkali metals.

3. Observe the reactivity of alkali metals and construct a detailed answer describing how their structure affects their reactivity.

4. Watch the demonstration carefully…

5. Why do you think the alkali metals behave this way?
Group 1 metals are VERY reactive The least reactive elements in the periodic table are those in Group 0 (the furthest column on the right) Can you explain why??

6. What part of an alkali atom makes it so reactive?
Answer- outer shell electron.

7. I wish my outside shell was empty…..
Sodium
Atom

8. Alkali metals are special metals because…….
They behave in this way because…….
Here is the electron configuration for a potassium atom to help explain this:
