Abstract:
A review is presented on recent progress of the application of molecular dynamics simulation methods with the inclusion of polarizability for the understanding of aqueous interfaces. Comparisons among a variety of models, including those based on density functional theory of the neat air-water interface, are given. These results are used to describe the effect of polarizability on modeling the microscopic structure of the neat air-water interface, including comparisons with recent spectroscopic studies. Also, the understanding of the contribution of polarization to the electrostatic potential across the air-water interface is elucidated. Finally, the importance of polarizability for understanding anion transfer across an organic-water interface is shown.

Covalent Bonds
When two atoms share electrons to complete their valence shells, they create a covalent bond. An atom's electronegativity—the force with which shared electrons are pulled towards an atom—determines how the electrons are shared. Molecules formed with covalent bonds can be either polar or nonpolar. Atoms with similar electronegativities form nonpolar covalent bonds; the electrons are shared equally. Atoms with different electronegativities share electrons unequally,...
