Name: _____________________________________________________ Date: __________ Period: _________ 9 Chemical Bonding (CHEMACTIVITY: Types of Bonding) How are the different types of chemical bonds described and quantified? 1. On your own…Read pp. 359-365 2. Describe what is meant by the term “bond”: 3. Compare and contrast ionic and covalent bonds: 4. Explain how covalent bonds can be polar or non-polar: 5. What is the relationship between a covalent bond’s polarity and the electronegativity values for the elements making the bond? 6. What is a “dipole moment”? What is represented by the symbols: δ+ and δ- ? 7. For each of the following molecules…explain whether the bond(s) formed within the compound are covalent (non-polar), polar covalent, or ionic. What information can be used to help you answer this question (HINT: There is a quantitative way, and a qualitative way) H2 H2O NaCl Essential Content and Skills: How do we compare and contrast ionic, covalent, and polar covalent bonds? How can we correctly and consistently determine the polarity of a bond between two atoms based on ∆E.N.? How can we explain the relationship between electronegativity and the existence of dipole moments within a molecule?
