What Is Polarity in Chemistry?....5

Gadolinium is the 64th element on the periodic table. It is a rare earth metal that does not occur on its own, but can be separated out from other metals. Use gadolinium to make the tubes for televisions, the coating on CDs and to help with X-rays using information from a science teacher in this free video on science and chemistry.

Hi, I'm Brian with ericksontutoring.blogspot.com. Today we're going to discuss gadolinium. So, gadolinium is the sixty fourth element on the periodic table. It is a rare earth metal that actually never occurs on its own naturally. But it is able to be separated out. Gadolinium is this sort of silvery white metal that is malleable which means you can press it in to a pancake. It's ductile, you can stretch it out kind of like in the wires or something like that and it has this luster or shine. So gadolinium is used in a lot of practical applications. It's used to make, or it's used in the tubes that go on color TVs, it's used as a coating on compact discs and computer processors. Gadolinium's used for nuclear submarine propulsion. It's used in MRIs and it helps out with X rays, so taking X rays, not X rays, the particle. It also, when you mix it with things like iron, it makes the material more workable. I think it's something like up to one percent increase in workability. It's also the best neutron collector. Of all the elements it's the best one. So, gadolinium, element sixty four, pretty useful.
