Draw the best Lewis structure for SF4. Use VESPR theory to predict the electron pair geometry and the molecular geometry around the central atom.    Electron Pair Geometry: ____________________ Molecular Geometry: ______________________

Use the following information to determine the Lewis structure, find the electron and molecular geometry of the molecule, determine the angle of the molecule, and determine the polarity. If the atoms are not the same, you may assume that the difference in their electronegativities are between 0.4 and 2.0. Atom information: A: 6 valence electrons, CANNOT exceed the octet. Further from fluorine on the periodic table than X. X: 6 valence electrons, CANNOT exceed the octet. Closer to fluorine on the periodic table than A. Molecule: AX,2- Electron Geometry: [Select] Molecular Geometry: [Select ] Bond Angle: [ Select] Polarity: [Select]

A model for BeBr, is shown in the chem3D window. BeBr, has linear geometry. ball & stick + labels Rotate the molecule until you have a feeling for its three-dimensional shape. Do the atoms in the molecule appear to lie on a straight line. What is the bond-angle at the central atom? degrees. For practice, type in the name of the geometry of the molecule:

Decide whether the Lewis structure proposed for each molecule is reasonable or not. molecule CIF 3 Yes, it's a reasonable structure. No, the total number of valence electrons is wrong. The correct number is: No, some atoms have the wrong number of electrons around them. The symbols of the problem atoms are: Yes, it's a reasonable structure. No, the total number of valence electrons is wrong. The correct number is: No, some atoms have the wrong number of electrons around them. The symbols of the problem atoms are: Yes, it's a reasonable structure. No, the total number of valence electrons is wrong. The correct number is: No, some atoms have the wrong number of electrons around them. The symbols of the problem atoms are: * If two or more atoms have the wrong number of valence electrons around them, just enter the chemical symbol for the atom as many times as necessary. For example, if two oxygen atoms have the wrong number of electrons around them, enter the symbol O twice. CIO₂ proposed…
