Transcript text: What is the formula for amme In the VSEPR model, the geometry of the regions defined by the electron pairs in the valence shell of an atom is called the electron-pair geometry. A. The Lewis diagram for $\mathbf{S b F}_{3}$ is: The electron-pair geometry around the $\mathbf{S b}$ atom in $\mathbf{S b F}_{\mathbf{3}}$ is $\square$ There are $\square$ unshared pair(s) around the central atom, so the geometry of the $\mathbf{S b F}_{\mathbf{3}}$ molecule is $\square$ .

Solution

Solution Steps

Step 1: Drawing the Lewis Structure for SbF₃

Antimony (Sb) is the central atom.
Sb has 5 valence electrons, and each Fluorine (F) has 7 valence electrons.
Total valence electrons: 5 (Sb) + 3×7 (F) = 26 valence electrons.
Place three F atoms around Sb and form single bonds.
Distribute remaining electrons to complete octets.

Step 2: Determining Electron-Pair Geometry

SbF₃ has 3 bonding pairs and 1 lone pair on Sb.
According to VSEPR theory, 4 regions of electron density (3 bonds + 1 lone pair) around Sb.
Electron-pair geometry for 4 regions is tetrahedral.

Step 3: Determining Molecular Geometry

With 1 lone pair, the molecular geometry is different from electron-pair geometry.
For 3 bonding pairs and 1 lone pair, the molecular geometry is trigonal pyramidal.
