When electrons are paired they create a magnetic field this is why transition metals have magnetic properties. True or false

Answer: false

Explanation:

It is the opposite.

Indeed electrons are spining in the atoms and that creates a magnetic field. Nevertheless, when the electrons are paired they spin in opposite directions and so the mangnetic fields are opposed leading to a net zero magnetic field.

It is when electrons are not paired that there is a net magnetic field and the metal exhibits magnetic properties.

So, the conclusion is that, in general, metals that have all the electrons paired do not have magnetic properties.
