AI Thread Summary
The discussion centers around the molecular structure of Nd2Fe14B, a rare earth-transition metal intermetallic compound used in permanent magnets. The participant initially sought information about the molecule's appearance and bonding, later sharing a link to a crystal image. The NdFeB structure is identified as a complex layered arrangement based on the SmCo5-type hexagonal unit. The inquiry stems from the participant's aerospace studies, specifically for a final paper on a nanomotor, where they aim to compare theoretical and experimental magnetic moment values of Nd2Fe14B. The need for clarity on iron isotopes and structural details is emphasized, as the participant is working on modeling the compound for further analysis.

Does anyone know how does this molecule looks like? (I study Aerospace, don't ask me why do i want to know :cry: )
How does those atomos connect with each other:
It's chemical formulae is:
Nd_2Fe_1_4B
 
Chemistry news on Phys.org
That's not needed right know, I've found it... if you want to know how the crystal of Nd_2Fe_1_4B looks like just chek

You really don't learn anything from that picture.

The NdFeB structure is a complex layered structure based on repetitions of the SmCo5-type hexagonal unit.

I'm not supposed to ask you why...but I'm really curious why an aerospace major would need information of the crystallography of rare earth-transition metal intermetallic based permanent magnet compounds.

I've worked a little with some of these(mostly structure and magnetization measurements)...that's why I'm curious.
 
Thank you and by the way...

That wasn't the only picture I've found... I've got other that is more explicit than the one I've pasted the link (that was just for people who didn't need to know how it looked like as much as i did)... but I'm still trying to figure out what is the diference between Fe isotopes symbolized by a full, blank, left side half full, right side half full and beyond...
What you told about the SmCo5-type hexagonal unit was a nice thing for me because i will be able to go further faster...
The reason I'm needing it it's because I'm doing a final paper about a nanomotor and i need to compare the teorethical values of magnetic moment of the Nd_2Fe_1_4B with the experimental ones (after some scaling laws). So I will model it to study in a program (3, to tell you the truth...). I could ask my professor but he only returns to school on wednesday... like everyone else (it's portuguese republic day on tuesday...)
 
It seems like a simple enough question: what is the solubility of epsom salt in water at 20°C? A graph or table showing how it varies with temperature would be a bonus. But upon searching the internet I have been unable to determine this with confidence. Wikipedia gives the value of 113g/100ml. But other sources disagree and I can't find a definitive source for the information. I even asked chatgpt but it couldn't be sure either. I thought, naively, that this would be easy to look up without...
I was introduced to the Octet Rule recently and make me wonder, why does 8 valence electrons or a full p orbital always make an element inert? What is so special with a full p orbital? Like take Calcium for an example, its outer orbital is filled but its only the s orbital thats filled so its still reactive not so much as the Alkaline metals but still pretty reactive. Can someone explain it to me? Thanks!!
