Description

This program considers the bonds formed when atoms share electrons (covalent bonding) The idea of filling electron shells to reach a more stable state is used to explain the formation of simple molecules such as water and methane. Shapes of molecules are explained by considering the repulsion between molecular orbitals. Further shapes are illustrated using CH4, NH3, and NH4. Double bonds (O2) and triple bonds (N2) are introduced. More complex molecules and methods used to simplify diagrams of molecules are discussed using glucose as an example.  Read more...
