The varicella zoster virus that causes chickenpox is the same virus that causes shingles. After a person experiences the chicken pox, the varicella zoster virus remains in the body in an inactive state near nerve tissue. At a later time, for unknown reasons, the virus reactivates and causes shingles.
In chemistry, polarity is a separation of electric charge leading to a molecule or its chemical groups having an electric dipole or multipole moment. Polar molecules interact through dipoleâdipole intermolecular forces and hydrogen bonds. Molecular polarity is dependent on the difference in electronegativity between atoms in a compound and the asymmetry of the compound's structure. Polarity underlies a number of physical properties including surface tension, solubility, and melting and boiling points.
