As mentioned in the Asimov short story "Pate de Fois Gras," this element's isotopes have the highest "packing fraction," that is, that they use the most energy per nucleon to maintain nuclear stability, making them the most stable.

The presence of this element in a stellar core is a star's death knell, as its fusion, like all elements lighter than it, is an endothermic process instead of exothermic. FTP, identify this element, of which Rudyard Kipling wrote "is the master of them all," the lightest ferromagnetic element and 90% component of Earth's core.
