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.

Magnetic Type of the elements
And then we have three 2p orbitals like that. Right so the sodium ion has this for an electron configuration. Let’s say we have two electrons and each of our electrons has spin up. And so let’s get some better definitions for paramagnetic and diamagnetic.
Magnetic Type for all the elements in the Periodic Table
Alright so let’s now turn the magnet on. The magnetic properties of a substance can be determined by examining its electron configuration: Because it has 4 unpaired electrons, it is paramagnetic. So we’ll put in your electrons.
So carbon is paramagnetic.

Finally let’s do sodium ion. Well of course that’s going to pull this side pwramagnetik. It’s like our paramagnetic sample has gained weight. So for diamagnetic all electrons are paired. If you’re seeing this message, it means we’re having trouble loading external resources on our website.
And of course it hasn’t gained weight, just experiencing a force.
Which one has the stronger bond? The term itself usually refers to the magnetic dipole moment. Notice for the ion now we have all paired electrons. Actually it produces its siamagnetik magnetic field in the opposite direction. That takes us to the 3s orbital. But we don’t pair those spins, right? And so let’s say we have. Because unpaired electrons can spin in either direction, they display magnetic moments in any direction.
So we turn the magnet on and the magnetic field lines go from north pole to south pole like that. Riamagnetik to the Pauli Exclusion Principle which states that no two electrons may occupy the same quantum state at the same time, the electron spins are oriented in opposite directions. And so we lose this one electron. This spin is negated when the electron is paired with another, but creates a weak magnetic field when the electron is unpaired.
If you write paramabnetik orbital notation. And so this would be pulled down into the magnetic field and so our paramagnetic sample is pulled into the magnetic field. So here we have a magnet.
And so let me go ahead and redraw it here. Image used with permission from Wikipedia. And unpaired electrons means that carbon is paramagnetic. But the sodium ion, we’ve lost one of those electrons.
So we talked about an example where we had two unpaired electrons. And we can figure out if a sample is paramagnetic or not by using this special balance that I have. So this weight’s gonna go up.
An unpaired electron means paramagnetic. We have unpaired electrons here for carbon when we draw out the orbital notation. Note that the poles of the magnets are aligned vertically and alternate two with north facing up, and two with south facing up, diagonally. So an electron is really just a tiny magnet.
So 2p1, 2p2, 2p3, 2p4, 2p5, 2p6. And so a diamagnetic sample would not be attracted to an external magnetic field.
Related questions How do electron configurations in the same group compare? So 1s2, 2s2, 2p6, 3s1 is the electron configuration for sodium.
Are #N_2# and #N_2^+# paramagnetic or diamagnetic? Which one has the stronger bond?
With one or more unpaired electrons, our paramagnetic sample is pulled into this external magnetic field that we’ve just turned on. Right so we would have our 1s orbital here. And we haven’t turned on the magnet yet.
