Gadolinium was separated by Marignac in 1880 who isolated the element from Yttrium. The element was named from the mineral from which it was found called Gadolinite.   It is also found in other minerals.  At room temperature gadolinium crystallizes a hexagonal form.  The metal is relatively stable in dry air and in moist air it tarnishes.
