Molecular compounds are formed when two non-metals share valence electrons forming a covalent bond. This results in two types of orbitals; bonding orbitals, where the valence electrons are shared between two nuclei, and non-bonding orbitals (lone pairs), where the valence electrons are localized to one nucleus. Molecules have definite geometric shapes which influence their chemical properties and behavior. The first step in understanding a molecule's geometry is in determining the connectivity of the atoms, and the types of orbitals each atom possesses. This can be conveniently done with Lewis dot structures, which account for all valence electrons by using lines between atoms to represent bonding electron pairs and dots to represent lone electrons.

Use PhET Simulation (see link below) to build electronic orbital models. Take screenshots and insert them in the table. Name the electron geometry. Use snipping tool or take a screenshot and insert in the table. Resize as needed. Use ONLY lone pairs.
VSEPR Lab Report is a group assignment. Make sure every member of your group participates!
