In contrast, molecular nitrogen, \(N_2\), has no unpaired electrons and is diamagnetic; it is therefore unaffected by the magnet. Diamagnetic. Recall that paramagnetic means it contains at least one unpaired electron and diamagnetic is the lack thereof. O2 is paramagnetic, with one. Paramagnetism is due to the presence of at least one unpaired electron in the molecule. The molecules of simple paramagnetic compounds usually contain odd.

But of course you could just have one unpaired electron.
So we have these two definitions. Let me change colors here. So we put those in. We have two electrons and they must be diamaynetik paired.
If you’re seeing this message, it means we’re having trouble loading external resources on our website. Alright so we have two electrons in the 1s orbital. So this whole part is pulled down. So an electron is really just a tiny magnet. And so this part’s gonna go up.
Finally let’s ciamagnetik sodium ion. Right so the sodium ion has this for an electron configuration. Contributors Jim Clark Chemguide. And let’s look at the definition for paramagnetic. Alright so two in the 1s orbital. We have unpaired electrons.
Well of course that’s going to pull this side down. Right so one electron in the 3s orbital. So while the sodium atom is paramagnetic, the sodium, I misspelled that. We have unpaired electrons here for carbon when paramagmetik draw out the orbital notation. And so a diamagnetic sample would not be attracted to an external magnetic field. And so this would be pulled down into the magnetic field and so our paramagnetic sample is pulled into the magnetic field.
So helium atoms I should say. We’ll notice one unpaired electron. So this situation here is paramagnetic.

What is Hund’s Rule?
Paramagnetism and diamagnetism
Right so we’re going to lose this outer electron here. Actually it produces its own magnetic field in the opposite direction. Moving charges produce magnetic fields. So something that’s paramagnetic has one or more unpaired electrons.
So let’s say that our paramagnetic sample is in here. See all questions in Electron Configuration. And unpaired electrons means that carbon is paramagnetic. Look for unpaired electrons There are no unpaired electrons. This spin is negated when the electron is paired with another, but creates a weak magnetic field when the electron is unpaired. Write down the electron configuration Draw the valence orbitals Identify if unpaired electrons exist Determine whether the substance is paramagnetic or diamagnetic.
The B atom has 2s 2 2p 1 as the electron configuration. So lemme see if I can draw that situation here. The following video shows liquid oxygen attracted into a magnetic field created by a strong magnet:.
