Let’s practice March 5, 2018 Read the paragraph, then answer the questions in PAIRS Take a look at the molecule on the right. What do you see? 2. Look at the Carbon on the left. What atoms are bonded to it? 3. Look at the second Carbon. What atoms are bonded to it? 4. Since carbon wants to have 8 valence (or outer electrons), and each carbon has 4 bonds, so how many electrons does each bond have? 5. Think about the duet rule. Do each of the three Hydrogens on the first Carbon satisfy this rule? Learning Target: I can Articulate how atoms bond together through practice and application of the octet rule
