Chemistry unit 3 review
Unit 3: Bonding. Bonds are connections between atoms. A solid grasp of valence shell electron pair repulsion (VSEPR) theory will help you understand how elements that differ by one or two atomic numbers behave. According to VSEPR theory, the number of electrons an element has corresponds with its chemical properties.polar covalent. 3. Multiple Choice. 1 minute. 1 pt.
