Physical Science Unit 2 Day 3

Learning Objective: Students will learn about the formation of molecules and compounds by building models and will analyze their properties using technical vocabulary (electronegativity, valence electrons, covalent bonds, ionic bonds).


Questions:

1. What is a molecule? 
2. What is a metallic bond?

3. For a bond to be covalent, the electronegativity difference between the atoms must be:
	A. less than 0.5. B. zero. C. less than 1.7. D. over 2. Exit Ticket for Day 3: Re-read the learning objective for today. How well do you think you met the objective on a scale of 1-5. Explain why you gave yourself this rating (analyze and synthesize).
