However, gadolinium can be found on rare occasions in the 0, +1 and +2 oxidation states. All four trihalides are known. All are white, except for the iodide, which is yellow. Most commonly encountered of the halides is gadolinium(III) chloride (GdCl 3). The oxide dissolves in acids to give the salts, such as gadolinium(III) nitrate.
However, gadolinite does not contain more than trace amounts of gadolinium. When Gadolin analyzed this mineral, he missed an opportunity to discover a second element: the element he thought was aluminium (alumina) was in fact beryllium (beryllia), an element that was not officially identified until 1798.
Gadolinium phosphide is an inorganic compound of gadolinium and phosphorus with the chemical formula GdP. [1] [2] Synthesis. Gadolinium phosphide can be obtained by ...
Gadolinium isotopes have 10 metastable isomers, with the most stable being 143m Gd (t 1/2 = 110 seconds), 145m Gd (t 1/2 = 85 seconds) and 141m Gd (t 1/2 = 24.5 seconds). The primary decay mode at atomic weights lower than the most abundant stable isotope, 158 Gd, is electron capture , and the primary mode at higher atomic weights is beta decay .

A 2015 study found gadolinium deposited in the brain tissue of people who had received gadodiamide. [8] Other studies using post-mortem mass spectrometry found most of the deposit remained at least 2 years after an injection and deposit also in individuals with no kidney issues. In vitro studies found it to be neurotoxic. [9]
