### VSEPR Theory and Molecular GeometryBelow is an example table summarizing the Valence Shell Electron Pair Repulsion (VSEPR) theory aspects of the methane molecule (CH₄):| Molecule or Molecular Ion | Lewis Structure | Valence Shell Electron Pairs | Bonding Electron Pairs | Nonbonding Electron Pairs | VSEPR Formula | Approx. Bond Angle | Geometric Shape ||----------------------------|-----------------|------------------------------|------------------------|---------------------------|---------------|-------------------|-----------------|| 1. CH₄ | H | 4 | 4 | 0 | AX₄ | 109.5° | tetrahedral || | .. | | | | | | || | H:C:H | | | | | | || | .. | | | | | | || | H | | | | | | |**Figure Explanation:**- **Lewis Structure:** This depicts the arrangement of atoms and electrons in the molecule. For CH₄, the carbon atom (C) is at the center with four hydrogen atoms (H) attached via single bonds.- **Valence Shell Electron Pairs:** Number of electron pairs in the valence shell of the central atom, including both bonding and nonbonding pairs.- **Bonding Electron Pairs:** Number of electron pairs that are participating in bonds.- **Nonbonding Electron Pairs:** Number of lone pairs of electrons on the central atom.- **VSEPR Formula:** The notation AX₄ indicates that the central atom (A) has four bonding pairs (X) and no lone pairs.- **Approximate Bond Angle:** The angle between adjacent bonds in the molecule. For CH₄, this is approximately 109.5°.- **Geometric Shape:** The spatial arrangement of the atoms. For CH₄, this arrangement is tetrahedral.### Practice Problem**3.** Complete the table (as outlined above) for the following molecules/molecular ions.

Show how these pairs of elements combine into octet-rule molecular compounds, as in the first example. First, draw their atomic Lewis structures, then use any number of these atoms to build an O.R. molecule, with multiple bonds if needed (you may not add a charge to make it O.R. as an ion!). Draw the O.R. Lewis structure, write its formula and chemical name. Atoms O.R. molecule Formula Name Carbon dioxide •¢. and ö. ö=c=ö CO2 H + Se I + S
