An MO diagram for other polyatomic molecules may show one or more bonds of interest in the molecules while leaving others out for simplicity. In polyatomic molecules we can have more than two atoms combining eg. In general a molecular orbital in a polyatomic system extends over all the nuclei in a molecule and it is essential if we are to understand and predict the spatial properties of the orbitals that we make use of the symmetry.
How to Draw MO Diagram. The concept of a molecular orbital is readily extended to provide a description of the electronic structure of a polyatomic molecule. S orbitals have a spherical shape and only one s orbital exists in the s-subshell.
3H A_1 with N A_1 bonding antibonding 3H Ex with N E bonding antibonding 3H Ey with N E bonding antibonding Nothing with N A_1. In general a molecular orbital in a polyatomic system extends over all the nuclei in a molecule and it is essential if we are to understand and predict the spatial properties of the orbitals that we make use of the symmetry properties possessed by the nuclear framework. These atomic orbitals contain no nodes.
In case of beryllium hydride there are 3 atoms overlapping simultaneously. First step is to determine which MO diagram were using.
