Information
Description
What It Is:
This is an electronegativity worksheet. It includes a chart with columns for the molecule, Lewis structure, drawing of the shape and indicating bond dipoles, the change in electronegativity (ΔEN) of bonds, polarity of bonds, whether the molecule is symmetrical, and the overall polarity of the molecule. The worksheet provides examples and asks students to fill in the missing information for various molecules such as NH3, N2, HBr, OCl2, SF6, SO2, SiCl4, CF2Cl2, XeF4, and C2H4. There is also a question at the bottom asking which binary compound would have the greatest ΔEN.
Grade Level Suitability:
This worksheet is suitable for high school (Grades 9-12), particularly for chemistry students. It requires understanding of Lewis structures, molecular geometry, electronegativity, and polarity, which are typically covered in high school chemistry courses.
Why Use It:
This worksheet reinforces understanding of electronegativity concepts and their application to determining molecular polarity. It helps students visualize molecular shapes, bond dipoles, and how these factors contribute to overall molecular polarity. It provides practice in drawing Lewis structures and predicting molecular properties.
How to Use It:
Students should use their knowledge of electronegativity values and Lewis structures to complete the chart. They will need to draw Lewis structures, determine bond dipoles, predict molecular geometry, and assess symmetry to determine the overall polarity of each molecule. Students can use textbooks or online resources to find electronegativity values and review relevant concepts.
Target Users:
The target users are high school chemistry students, teachers looking for supplemental materials on electronegativity and molecular polarity, and students preparing for chemistry exams.
