Jones et al at Oak Ridge discovered that one neutron-rich isotope of this element is doubly magic, a property shared by its 100 and 132 isotopes. A compound containing this element bonded to alkyl groups is decomposed by AIBN in the second step of the Barton-McCombie decarboxylation. Its dichloride mixed with hydrochloric acid is used to synthesize aldehydes from nitriles in the Stephens synthesis, and this element's tributyl hydride is used to transform halides to the corresponding alkane. A classic example of the inert pair effect is the fact that this element's dichloride is easily (*) oxidized. A palladium-catalyzed reaction similar to the Suzuki coupling uses an alkylated derivative of this element to couple halides or pseudohalides to alkyl groups and is called the Stille reaction. This element, which comes in an alpha, or "gray", and beta, or "white", allotropes, is extracted from the ore cassiterite, and the Meissner effect was first observed in superconductors of this element. For 10 points, name this element which combines with copper to form bronze
