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

Discover the reactivity of alkaline earth metals with water and HCl, alkali metals with water and oxygen, and patterns on the periodic table based on reactivity. Explore relationships between atomic radius, ionization energy, and elements that break the norm. Learn how ionization energy and atomic radius change across the periodic table.

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

  2. 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 Metals Patterns on the Periodic Table based on Reactivity?

  3. What relationships and patterns did we discover on the periodic table with • Atomic Radius, Ionization Energy? • Are there any elements that break the mode?

  4. 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

  5. Atomic Radius • Decreases from left to right • Increases from top to bottom
