What did you discover in the lab and doing the worksheet about….

• Reactivity of Alkaline Earth Metals with Water?• Reactivity of Alkaline Earth Metals with HCl?• Reactivity of Alkali Metals with water?• Reactivity of Alkali Metals with oxygen?Relationship of reactivity between Alkali Metals

and Alkaline Earth MetalsPatterns on the Periodic Table based on

Reactivity?

• What relationships and patterns did we discover on the periodic table with

• Atomic Radius, Ionization Energy?• Are there any elements that break the

mode?

Just to make sure we’re on the same page

• Ionization energy is the energy it takes to remove one valence electron from an element

• In general Increases from left to right across the periodic table

• Decreases from Top to bottom

Atomic Radius

• Decreases from left to right• Increases from top to bottom
