diamagnetism

[Clara Cho 2K]

what is diamagnetism?

[Christine Honda 2I]

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.

[Akshay Chellappa 1H]

In addition, a compound is diamagnetic if it only contains paired electrons and is not attracted to a magnetic field.

[AMahadi]

what is the difference between diamagnetism and paramagnetism?

[preyasikumar_2L]

Diamagnetic atoms/compounds (and atoms) have paired electrons and are repelled from magnetic fields. (Paramagnetic atom/compounds are the opposite)

Is there any way to know for sure if the substance is magnetic other than prior knowledge like is there a formula we need to know?
