How hard is gadolinium?

Answer 1

Gadolinium is relatively stable in dry air, but in moist air it tarnishes with the formation of a loosely adhering oxide film which flakes off and exposes more surface to oxidation. The metal reacts slowly with water and is soluble in dilute acid. Gadolinium has the highest thermal neutron capture cross-section of any known element

Answer 2

Gallium, one of the so-called poor metals, is "somewhat" reactive as metals go. It is not found free in nature, and will readily form compounds, which is a reflection of its electronegativity of 1.81 (Pauling scale). Use the link below for more information.

Answer 3

AnswerGadolinium is "anti-radioactive." Rather than emitting particles like a good radioactive element should, it absorbs them so well they line nuclear reactors with it.

Here's a cool application of gadolinium: For some reason, tumors LOVE gadolinium. If you give someone an IV injection of gadolinium solution, the tumor will grab all it can. Then you aim a neutron source at the area of the tumor, and the gadolinium pulls the neutrons into the tumor, which destroys it.

Gadolinium is very paramagnetic--in the presence of a magnetic field, it becomes magnetic itself. Couple that with abnormal tissue's affinity for the element, and you get the best MRI contrast medium there is.

AnswerFor most practical purposes, gadolinium can be regarded as not radioactive. 77.94% of gadolinium is of stable isotopes. 22.06% is of two radioactive isotopes, but the shorter half life is still very long at 108,000,000,000,000 years. There are radioactive synthetic isotopes, as there are with all other elements.

Answer 4

yes iy can actually be harmfuk if you use too much of it... :)

Answer 5

Yes, gadolinium is a chemical element with symbol Gd and atomic number 64. Gadolinium is a silvery-white, malleable, and ductile rare earth metal.

Answer 6

It is not hard at all!
