DIAMAGNETIK DAN PARAMAGNETIK PDF
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.

So while the sodium atom is paramagnetic, the sodium, I misspelled that. An unpaired electron means paramagnetic. And let’s look at some elements. The magnetic properties of a substance can be determined by examining its electron configuration: And then we have three 2p orbitals like that.
Look for unpaired electrons There are no unpaired electrons. Right, so that would be 1s2. Right so that’s like a tiny magnet with its own magnetic field. So we have 1s2 which means we have two electrons in a 1s orbital. That takes us to the 3s orbital. This process can be broken into three steps: But we don’t pair those spins, right? If you have a situation where paramagmetik have one electron with spin up and one electron with spin down, the magnetic fields of those electrons cancel each other out.
I have this picture of this balance drawn down here.
Magnetic Type for all the elements in the Periodic Table
This capability allows diamagnetk atoms to be attracted diamzgnetik magnetic fields. We have unpaired electrons.
What is the electron configuration for a nitride ion? And so we lose this one electron. Whether a compound can be ferromagnetic or not depends on its number of unpaired electrons and on its atomic size.
We don’t pair those spins. And so let’s get some better definitions for paramagnetic and diamagnetic. This spin is negated when the electron is paired with another, but creates a weak magnetic field when the electron is unpaired. And let’s look at the definition for paramagnetic.
So lemme see if I can draw that situation here.
And so we call this situation diamagnetic. And then we have, we’re in the 2p1 and then 2p2.
Finally let’s do sodium ion. So 1s2, 2s2, 2p2 is the electron configuration for carbon. So the sodium atom has equal numbers of protons and electrons. And so that’s going to pull and our balance is going to rotate about this axis, right? So it’s actually weakly repelled by an external magnetic field. So here we have a magnet. What is the electron configuration for a sodium ion? Right what does that do to our balance? Well of course that’s going to pull this side down. Ferromagnetism Permanent Magnet Ferromagnetism is dxn basic mechanism by diamagnerik certain materials such as iron form permanent magnets.
If we did that on our orbital notation, right?
And so we have. And of course it hasn’t gained weight, just experiencing a force. We have one, two, three, four, five, six. Indicate whether F – ions are paramagnetic or diamagnetic. Therefore, Br has 1 unpaired electron.
Are #N_2# and #N_2^+# paramagnetic or diamagnetic? Which one has the stronger bond?
Let me change colors here. Chlorine Atoms Step 1: So I’m assuming you already know how to write your electron configurations. The O atom has 2s 2 2p 4 as the electron configuration.
And we can figure out if atoms or ions are paramagnetic or diamagnetic by writing electron configurations. So we have, if we have spin up, we have spin down. Alright so two in the 1s orbital. And so the magnetic fields cancel. So 1s2, 2s2, 2p6, 3s1 is the paraamagnetik configuration for sodium.

The following video shows liquid oxygen attracted into a magnetic field created by a strong magnet:. The B atom has 2s 2 2p 1 as the electron configuration. Well an fan is a moving charge.
