13.1 Transition Metals, their Complexes and Magnetism [HL IB Chemistry]

error: 2:55 should 4s2 3d5 not 4s2 4d5

Ferromagnetic = Fe,Ni,Co - attracted to magnets
Paramagnetic - at least one lone electron - weakly attracted to magnets
Diamagnetic - very weakly repelled from magnets, all electrons in pairs.

Love the way it is explained! If only my teacher could explain every chapter like these videos...

Dear sir you are truly awesome at teaching. It’s so magical .

[victormoncada]

I LOVEE your channel my dude. Thank you so much

Hi Mr. Thornley, at min 3:01 the electron configuration for Mn should be: 4s2 3d5 and so, Mn2+ should be: 3d5, not 4d5 (unless I missed something out) and yeah I reaaaally love your videos :))

So is there like a specific cut-off in the spectrochemical series that divides the ligands which produce such a large energy gap that the electrons fall down and pair up below, or are the only 2 ligands that do this CO and CN-? Also, when this happens, are the complexes still colored or do they lose their color?

Thanks for the help!

What is a domain? I've been looking through 2 of my text book and one of the revision guide but none of them gives me a reason why only iron, cobalt and nickel are ferromagnetic and what is domain....

3:28 i thought cobalt was ferromagnetic?

[hydrogen]

Why is CoCl2 paramagnetic and not ferromagnetic?

[hyungjunkim]

Does Ferromagnetism only apply to the pure metals of Fe, Ni and Co? Because you said that CoCl2 is paramagnetic, but Co is ferromagnetic

[acedes]

Why is iron ferromagnetic but manganese is paramagnetic?

[hermannklein-hessling]

Why does CO have an oxidation state of 0?

[samisabbah]

In the beginning of the video you say cobalt is ferromagnetic and then in the next part you say that it is paramagnetic?
