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?

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

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

Watch the demonstration carefully…

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??

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

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

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:
