Scratch visibility of polymers measured using optical imaging by Rangarajan, P.; Sinha, M.; Watkins, V.; Harding, K.; Sparks, J. / Polymer Engineering and Science. For reflection, the incident light wave is resolved into components in the. and normal to the. (the plane of the surface).
The intermolecular forces and bonds of water are many. All molecules have Van der Waal or London dispersion forces. Since the OH bonds are polar, dipole-dipole interactions exist. Due to the bonding of H to the O, hydrogen bonding is present between molecules. That is all, ionic bonding does not exist for water. Hydrogen and hydroxide do not completely separate into ions.
An ionic bond is a chemical bond between two atoms in which one atom seems to donate its electron to another atom. Covalent bonds, on the other hand, appear to involve two atoms sharing electrons reach a more stable electron configuration. Some compounds contain both ionic and covalent bonds. These compounds contain polyatomic ions. Many of these compounds contain a metal, a nonmetal, and also hydrogen.
