  2. Chemical polarity - Wikipedia

    en.wikipedia.org/wiki/Chemical_polarity

    2, has zero dipole moment, while near the other extreme, gas phase potassium bromide, KBr, which is highly ionic, has a dipole moment of 10.41 D. [9] [page needed] [10] [verification needed] For polyatomic molecules, there is more than one bond. The total molecular dipole moment may be approximated as the vector sum of the individual bond ...

  3. Electric dipole moment - Wikipedia

    en.wikipedia.org/wiki/Electric_dipole_moment

    A physically more realistic modeling of p(r) would have the dipole moment density drop off rapidly, but smoothly to zero at the boundary of the confining region, rather than making a sudden step to zero density. Then the surface charge will not concentrate in an infinitely thin surface, but instead, being the divergence of a smoothly varying ...

  4. Dipole - Wikipedia

    en.wikipedia.org/wiki/Dipole

    The linear molecule CO 2 has a zero dipole as the two bond dipoles cancel. Potassium bromide (KBr) has one of the highest dipole moments because it is an ionic compound that exists as a molecule in the gas phase. The bent molecule H 2 O has a net dipole. The two bond dipoles do not cancel.

  5. Neutron electric dipole moment - Wikipedia

    en.wikipedia.org/wiki/Neutron_electric_dipole_moment

    The neutron electric dipole moment (nEDM), denoted d n, is a measure for the distribution of positive and negative charge inside the neutron.A nonzero electric dipole moment can only exist if the centers of the negative and positive charge distribution inside the particle do not coincide.

  6. Electron electric dipole moment - Wikipedia

    en.wikipedia.org/.../Electron_electric_dipole_moment

    The electron's electric dipole moment (EDM) must be collinear with the direction of the electron's magnetic moment (spin). [1] Within the Standard Model, such a dipole is predicted to be non-zero but very small, at most 10 −38 e⋅cm, [2] where e stands for the elementary charge.

  7. Boron trifluoride - Wikipedia

    en.wikipedia.org/wiki/Boron_trifluoride

    The molecule has no dipole moment by virtue of its high symmetry. The molecule is isoelectronic with the carbonate anion, CO 2− 3. BF 3 is commonly referred to as "electron deficient," a description that is reinforced by its exothermic reactivity toward Lewis bases.

  8. Carbon tetraiodide - Wikipedia

    en.wikipedia.org/wiki/Carbon_tetraiodide

    It has zero dipole moment due to its symmetrically substituted tetrahedral geometry. Properties, synthesis, uses

  9. Nuclear magnetic moment - Wikipedia

    en.wikipedia.org/wiki/Nuclear_magnetic_moment

    The nuclear magnetic moment is the magnetic moment of an atomic nucleus and arises from the spin of the protons and neutrons. It is mainly a magnetic dipole moment; the quadrupole moment does cause some small shifts in the hyperfine structure as well. All nuclei that have nonzero spin also have a nonzero magnetic moment and vice versa, although ...
