paramagnetic vs diamagnetic (this is getting old)

chad says paramagntic substances are deflected by magnetic fields. destoyer says diamagnetic are weakly repelled by magnetic fields. wiki says that paramagnetic is attracted to a magnetic fields. and another sdn poster says that paramagnetic alligns with magnetic field. could someone weigh in on this please?

 

[rmm30]

anybody else take notes on chads videos and have it written down that paramagentic is deflected by a magnetic field? im starting to think i copied these notes wrong

I took notes on his vids and I still have a subscription. If you know what vid it is, i'll take a look..

paramagnetic = attracted
diamagnetic = repelled

but i took good notes on chads stuff, ill double check them after work and cross reference it with my gen chem book just to be 100%

In Chad's video (1.2 Electron Config), he does say paramagnetic is deflected, but he also says diamagnetic "not so much" and that it may be very slightly repulsed. So what Chad said is the same as Destroyer in regard to diamagnetism.

In 5 steps to a 5 in AP Chemistry it says this:

Paramagnetism, the attraction to a magnetic field, is due to the presence of unpaired electrons; diamagnetism, the slight repulsion from a magnetic field, is due to the presence of only paired electrons.

This site at UCDavis also agrees with paramagnetism being attracted:

I don't have my chemistry textbook, else I'd confirm Chad made a mistake, and that paramagnetic is actually attracted not deflected.

alrighty, looks like chad may have misspoken. in my notes I have him saying a paramagnetic atom is going to be deflected and a diamagnetic atom is not deflected as much.

however my gen chem textbook defines a paramagnetic substance as one thats attracted to a magnetic field, and a diamagnetic substance as one thats slightly repelled. thats from chemistry:the central science 11th. ed. by brown.

dunno how that slipped by me, i just took massive amounts of notes on chad's stuff and havent gone over them just yet.

Just wanted to add this, as it is a direct reply from Chad regarding this issue on his video, for clarification purposes:

Chad: Sorry for the confusion. I actually meant the same thing. I meant that a paramagnetic species will be deflected off of its trajectory due to an attraction to a magnetic field whereas a diamagnetic species will not (very slight repulsion actually).

Paramagnetic species align WITH the magnetic field because of unpaired electrons, which induce a magnetic momentum into them.

Diamagnetic species will... half align with the field while the other half will point in the opposite direction. Since all electrons are paired, they cannot have a magnetic momentum induced into them.


TBR!

thanks guys, thats been driving me crazy for a week. moving on...
