2 Warm-Up 9/16 What is the Lewis Dot Plot for the following… 1. Nitrogen, Oxygen, Fluroine and Helium. 2. Why do you think Helium only has two dots???

3

4 How many electrons/protons does Helium have? TWO! How can it have more than two valence electrons?!?!

5 Lab Day! We’re down to the end…Quiz 1. Read allowed first paragraph. 2. Group Work 3. Summary-Individual

6 Quiz TOMORROW! Can you… Identify if it is a metal, nonmetal, or metalloid? Identify the # of valence electrons (I will give you a periodic table). Draw a Lewis Dot Diagram Identify if the following compounds as ionic or covalent.
