The paramagnetic behaviour of b2 is due to
Webb(i) Transition metals show paramagnetic behaviour. Paramagnetism arises due to the presence of unpaired electrons with each electron having a magnetic moment associated with its spin angular momentum and orbital angular momentum. However, in the first transition series, the orbital angular momentum is quenched. Webbadiabatic demagnetization, process by which the removal of a magnetic field from certain materials serves to lower their temperature. This procedure, proposed by chemists Peter Debye (1926) and William Francis Giauque (independently, 1927), provides a means for cooling an already cold material (at about 1 K) to a small fraction of 1 K. The mechanism …

WebbAnswer (1 of 10): All oxygen is paramagnetic. Ordinary atmospheric oxygen gas is paramagnetic, but because its density is so low, its mass is very small and its paramagnetic behaviour is difficult to measure. Liquid oxygen, on the other hand, is dense enough that it's paramagnetic properties are...

Any time two electrons share the same orbital, their spin quantum numbers have to be different. Whenever two electrons are paired together in an orbital, or their total spin is 0, they are diamagnetic electrons. Atoms with all diamagnetic electrons are called diamagnetic atoms. A paramagnetic electron is an unpaired electron.

Constituent atoms or molecules of paramagnetic materials have permanent magnetic moments (dipoles), even in the absence of an applied field. The permanent moment generally is due to the spin of unpaired electrons in atomic or molecular electron orbitals (see Magnetic moment). In pure paramagnetism, the dipoles do not interact with one another and are randomly oriented in the absence of an external field due to thermal agitation, resulting in zero net magnetic moment.
