The two ways in which this is viewed are expressed by the valence bond (VB) and molecular orbital (MO) methods. In VB theory, the atomic orbitals essentially keep their character and interact by overlapping. In MO theory, the orbitals essentially lose their character as orbitals form that ...
Bonding and Bonding and Molecular Structure Molecular Structure Goals: 1. Understand the differences between ionic and covalent bonds. 2. Draw Lewis electron dot structures for small molecules and ions. 3. Use the valance shell electron-pair repulsion theory (VSEPR) to predict the shapes of simple...

He proposed that teaching be started from metallic structure to ionic structure, then giant covalent structure and finally simple molecular structure. During teaching, teachers should be cautioned about the use of language, the undue emphasis on the role of atoms (atomic ontology), the explication ...

Structure and Bonding in Organic Compounds 1.11 The Hydrogen Molecule The molecular orbital containing the bonding electrons in H2 results from the overlap of two 1 s atomic orbitals. The molecular orbital of the hydrogen molecule encompasses both nuclei. They are separated by an optimum distance, ...
