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?
