WebWhen you place a molecule with an electric dipole in an electric field, a force acts to turn the molecule so that the positive and negative ends line up with the field. The magnitude of the turning force is given by the formula µ = q × d where q is the amount of charge and d is the distance between the two charges. µ is the turning moment. WebIn a chemical formula, we use the elemental symbols from the periodic table to indicate which elements are present, and we use subscripts to indicate how many atoms of each element exist within the molecule.

WebWhen we say something is polar, it has a very specific meaning. It means that there is a spatial separation of charges, or a dipole moment. In the simplest case, this is given by: μ = Q r Where μ is the dipole moment, Q is the charge on each pole (equal and opposite) and r is the distance between the charges. WebHow do you know which molecule is more polar? The larger the difference in electronegativity between the two atoms , the more polar the bond. To be considered a polar bond, the difference in electronegativity must >0.4 on the Pauling scale.
