silicon atom has 14 electrons with 2 unpaired electrons in 3p orbital.
why silicon is not magnetic?
why silicon is not magnetic?
I know, but that was not the point. I was talking about looking for a classification of magnetic systems and how you can see what is what based upon electronic configurations.Gokul43201 said:Not really. Paramagnetism and diamagnetism (unlike ferro, ferri and antiferro-magnetism) are not many-body effects and their susceptibilities can be calculated pretty well from the single atom case (perhaps incorporating corrections from crystal fields).
Neither do II know of no case where say, a paramagnetic solid becomes diamagnetic upon melting into a liquid (which is not to say that such a thing doesn't exist - only I'd be pretty surprised if it did).
How is this an illustration of a many-body effect ?sniffer said:paramagnetism is a many body effect.
iron when heated up to its crtitical temperature will become paramagnetic of course.
What you've done here, is crudely (because there are errors) describe anti-ferromagnetism (not paramagnetism), which is, in fact, due to orbital overlap. But if you still insist that paramagnetism is due to orbital overlap, please explain to me how you have paramagnetism in dilute gases ?paramagnetic is in fact due to orbital overlap!
when one unpaired orbital of an atom overlaps with its neighbouring atom, these two unpaired orbital will merge into single wave function and pauli exclusion principle applies. thus if one spin up, the other will be spin down, and the magnetism cancels.
What is an "unpaired orbital" ?if suppose there are two unpaired orbital in each atom you will end up with:
If u and d refer to two unpaired electrons, then by making them be of opposing spins you are violating Hund's first rule, and hence are NOT constructing a "legal" ground-state. What you've constructed is a fictional ground state.atom1 atom2 atom3 atom4 etc...
ud du ud du ud...
Please name one such book, with the page number where I will find this.so pauli exclusion applies within an atom and among orbital overlaps as well.
you can find this in many books on magnetism.
Silicon is a non-magnetic element, meaning it does not produce its own magnetic field. This is due to its atomic structure, which does not have unpaired electrons necessary for magnetism.
No, silicon cannot be made magnetic. It is a diamagnetic material, meaning it is not affected by external magnetic fields.
Silicon's atomic structure has a completely filled outermost electron shell, making it stable and non-reactive. Additionally, it has no unpaired electrons, which are necessary for producing a magnetic field.
No, there are no forms of silicon that are magnetic. Adding impurities or alloys to silicon may change its magnetic properties, but pure silicon remains non-magnetic.
The lack of magnetic properties in silicon makes it a useful material for electronic devices, as it does not interfere with magnetic fields. It also allows for the production of non-magnetic computer chips, which are essential for many technological applications.
