Gadolinium - Periodic Table of Videos

[TheItalianPerson]

is it radioactive?

[TheDrraspberry]

@TheItalianPerson There are radioactive isotopes, but the most common form of gadolinium is not radioactive. It's used in MRI because the 3+ ion of it is the most magnetic material on the periodic table.

I just bought a chunk of the stuff today, 85g/70$cad. Its a pretty enough chunk, but the varying degrees of oxidation make some of it look like Europium.

[bbawor]

Really useful, thanks:)

[samolishus]

i wanted to learn about gadolinium but most the information you gave i had already known. i ask please remake this video with more information about gadolinium.

[rocktunes]

Get rid of that lame accent. I used to have one but got rid of it. Otherwise great video. Thanks!

[onthecuttingedge2005]

hey i read that book a decade ago. cool beans.

[onthecuttingedge2005]

take one thermal vacuum bottle, fill it a little with liquid Helium or liquid nitrogen, on the inside top of the vacuum bottle put a strong magnet up top. see what happens when the Gadolinium exchanges temperature.

I actually have a 50 g sample of gadolinium, it's a dark-silvery metal. It transitions from a paramagnetic to a ferromagnetic metal at 292 K, so it's fun to put it in the freezer and later put a fridge magnet on it! As usual, another A+ video.

[JonathanTheAlchemist]

I have a 50 g sample of gadolinium, it is a rather dense metal. A fun experiment is to put the metal in the fridge because It becomes ferromagnetic at 292 K.

GADOLINIUM COMPLETELY SCREWED UP MY LIFE!!! I HATE GE!!!

[noblessus]

@villainlovesjohnny What happened?

[TheRolemodel1337]

i would like to have these guys as chemistryteachers .p

[W1049]

One of the properties I find fascinating is the Curie Effect which is a unique property of the metal

[tracy10UT]

Very interesting! Thank you.

Gd (in the forum of the soluble nitrate) is also used as a soluble poison to shut down nuke reactors - since its soluble it can be dissolved in the cooling fluid and quickly dispersed

the professor has a bottle of vodka right next to his dog toys.

[Sedokun]

How You dare! It's mineral water! =))))

[douro20]

Mendeleev vodka, which he brought back from Russia.

[DecommMan]

Sweet.

I use Gadolinium in Nuclear Medicine, a radioactive form of it, to determine the attenuation of the radionuclides in patients to see how long you need to scan a patient in order to get a good picture. Just so you know!

[thePENANCE]

You're 22 years old stop bullshitting

[spayum2]

Did it ever occur to you that he might be a medical student?

[thePENANCE]

He's 22 years old, and students don't use nuclear medicine at such a young age, they use it for maybe PhD or Post-Doctorates

[manzilla86]

No, actually I had a course in Nuclear Chemistry since my major is Nuclear Medicine Technology. I found the course highly enjoyable, and since it was a ton of work, I don't mind throwing in tidbits of info when I get the chance. Also, there wouldn't be too much of a need to take Nuclear Chemistry if you were a medical student unless you were specializing in Radiology or Nuclear Medicine.

[Sedokun]

"radioactive form" ? You mean oxidated form, cause MRI used Ga3+ based contrasts, like Gadodiamide.

[Sedokun]

Sorry, not Gallium, Gd3+.

[AlmightScoop]

Gadolinium. I read that there are people who are attaching Gadolinium to cocaine molecules in order to visualise where in the brain cocaine goes, by using its MRI properties. Any voulenteers for that research?

[AlmightScoop]

about what? It was an article in New Scientist about 3 weeks ago. Presumably you do have a clue? Judging from your subscription to the 'Labyrinth of the Psyconaught' and its occult content, I suppose you don't.

[thePENANCE]

loser

hahaha

learn to spell

hahaha
