Which orbital is non directional?
They are non directional because they are spherical in shape and probability of finding electrons at a particular distance from the nucleus is same in all directions.
Define dipole moment. Explain factors affecting dipole moment.
Dipole moment is the product of magnitude of the charge (q) and the distance between the centre (d) of the charges is called dipole moment.
It is usually denoted by μ.
The factors affecting dipole moment are:
