Tetrahedral electron pair geometry

In a tetrahedral the four groups of electrons around the central atom are as far apart as possible. The angles between the groups of electrons in a tetrahedral are each 109.5o.

Carbon tetraiodide (CI4) is an example of a molecule characterized by tetrahedral electron pair geometry. It is composed of one carbon and four iodine atoms positioned at the corners of a tetrahedron. In the following structural formula of carbon tetraiodide arrows are pointing to the four groups of electrons around the central carbon atom.
