Question
The image displays a table designed for educational purposes, focusing on the analysis of molecular structure and geometry. The table is organized into eight columns and six rows, with the following headings:

1. **Molecule/Ion**: List of chemical species being analyzed.
   - [PF₆]⁻
   - [BeF₄]²⁻
   - Br₂(CH₃)₂Se
   - H₂O
   - SO₂
   - Cl₂CF₂I

2. **# valence electrons**: Number of valence electrons in each molecule or ion.

3. **Lewis Structure**: Space for drawing the Lewis dot structure for each molecule or ion.

4. **Electron Domain Geometry**: Describes the geometric arrangement of electron domains around the central atom.

5. **Molecular Geometry**: Describes the three-dimensional shape of the molecule or ion.

6. **Predicted Angle/s**: Lists the theoretical bond angles based on geometry.

7. **Measured Angles**: Space to record actual measured bond angles.

8. **Justification for agreement or deviation?**: Space to explain any discrepancies between predicted and measured angles.

The table is likely used in a chemistry education context to help students understand the relationships between electron configuration, molecular shape, and bond angles. It facilitates the process of predicting and explaining molecular geometry using theoretical and empirical data.
