Answer 1

Question #48960, Chemistry, Inorganic Chemistry

Write the formula for dipole moment and give its unit.

Answer:

The simplest system of charges, having a certain (which does not depend on the choice of the origin) is nonzero dipole moment - a dipole (two point particles with the same largest dissimilar charges). Electric dipole moment of such a system is the product of the modulus of the positive charge on the distance between the charges and directed from the positive to negative charge:

$$\mathbf {p} = q \mathbf {l},$$

q-the amount of positive charge, I-vector between charges.

For a system of N particles electric dipole moment is

$$\mathbf {p} = \sum_ {i = 1} ^ {N} q _ {i} \mathbf {r _ {i}},$$

Unit:

[C·m] or debye [D]

$$1 \mathrm {D} = 3, 3 3 5 6 4 0 9 5 \cdot 1 0 ^ {- 3 0} \mathrm {C} \cdot \mathrm {m}$$
