How can the VSEPR model be used to determine the shape of a covalent molecule? 1. Since molecular shape is based on the electronegativity of the central atom, the VSEPR theory predicts the shape based on the calculated difference in electronegativity of the central atom with the other atoms in the molecule.

2. Since molecular shape is based on the number of electrons shared between each element in the compound, the VSEPR theory predicts the shape based on the number of elements present in the molecule and the number of bonds they share.

3. Since molecular shape is based on the electrons surrounding the central atom, the VSEPR theory predicts the shape of the molecule based on the bonding electron pairs and lone electron pairs around the central atom.

4. Since molecular shape is based on the elements present in the bond, the VSEPR theory predicts the shape of the molecule based on what type of elements are present, such as whether the elements are metals or nonmetals.
