Answer Key for Molecule Polarity PhET Lab
Here is a comprehensive answer key to help you navigate through the PhET lab on molecule polarity. This key includes explanations for various scenarios and questions you might encounter.
1. Question: What happens to the polarity of a molecule when you add a highly electronegative atom like fluorine?
Answer: Adding a highly electronegative atom like fluorine increases the polarity of the molecule. The fluorine atom attracts electrons more strongly, creating a more significant charge separation within the molecule.
2. Question: How does the shape of a molecule affect its polarity?
Answer: The shape of a molecule plays a crucial role in determining its polarity. Symmetrical molecules tend to be non-polar because the dipole moments cancel each other out. In contrast, asymmetrical molecules are often polar because the dipole moments do not cancel out.
3. Question: What is the difference between a polar and a non-polar molecule?
Answer: A polar molecule has an uneven distribution of charge, with one end being slightly positive and the other slightly negative. Non-polar molecules have an even distribution of charge, meaning there is no significant charge separation.
4. Question: How can you determine if a molecule is polar or non-polar?
Answer: To determine if a molecule is polar or non-polar, you need to consider both the electronegativity of the atoms and the molecular geometry. If the molecule has a symmetrical shape and the electronegativity differences are minimal, it is likely non-polar. If the molecule is asymmetrical and has significant electronegativity differences, it is likely polar.
5. Question: What role does electronegativity play in molecule polarity?
Answer: Electronegativity is a measure of an atom's ability to attract electrons. In a molecule, the difference in electronegativity between atoms determines the polarity. A larger difference in electronegativity leads to a more significant charge separation, making the molecule more polar.

3. Question: How can you distinguish between a polar and a non-polar molecule?
Answer: To distinguish between a polar and a non-polar molecule, consider both the electronegativity of the atoms and the molecular geometry. If the molecule has a symmetrical shape and minimal electronegativity differences, it is likely non-polar. If the molecule is asymmetrical and has significant electronegativity differences, it is likely polar.
4. Question: What factors influence the polarity of a molecule?
