Physical Science 2 Unit 2 Day 4

Day Starter
Objective: Students will diagram and describe Lewis Dot Structures and bonding on a group 3,2,1 chart using the words ionic bond, covalent bond, oxidation number, valence electrons, electronegativity.

Question:
1) What is oxidation number? Give an example.
2) When do ionic bonds form? Between what elements?
3) When do covalent bonds form? Between what elements?

Exit Ticket:
What do oxidation numbers have to do with chemical bonding? Use the following topic sentence starter "Oxidation numbers are related to bonds because...." and the words valence electrons and Lewis Dot Structures to write a perfect 3 sentence paragraph.
