Thus, the valence electrons in the Lewis dot structure of [CO3]2- = 1(4) + 3(6) + 2 = 24 valence electrons. VSEPR theory predicts these distortions by establishingthat alone pair of electrons occupies a larger region of space than the electrons in bonding pair. Again, there are slight deviations from the ideal because lone pairs occupy larger regions of space than do bonding electrons. Predicting Electron Pair Geometry and Molecular Structure. 1. This means there are three locations for electrons. There are two different atoms present in [CO3]2- ion i.e., the carbon (C) atom and the oxygen (O) atoms. Use VSEPR theory predictions to determine the molecular shape of 3 atoms with 1 lone electron pair. Save my name, email, and website in this browser for the next time I comment. Helmenstine, Anne Marie, Ph.D. "Valence Shell Electron Pair Repulsion Theory." The structure that includes only the placement of the atoms in the molecule is called the molecular structure. Consequently, the central C-atom still needs 2 more electrons to achieve a complete octet. Thus the ideal electron geometry of carbonate [CO3]2- ion is trigonal planar. Here, we can follow the AXn notation to find out the exact molecular geometry of CO32- ion. Dr. Helmenstine holds a Ph.D. in biomedical sciences and is a science writer, educator, and consultant. Two "election clouds" or regions of electron density around a central atom in a molecule form a linear geometry; three electron cloudsform a trigonal planar geometry; four electron cloudsa tetrahedral geometry; five electron cloudsform a trigonal bipyramidal geometry; and six electron cloudsform an octahedral geometry (Notice that five and six electron clouds correspond to situationsof octet rule expansion around the central atom).
