Chemistry of Fermium

From evidence detected in the debris of the first hydrogen bomb test, the Berkeley team of Ghiorso et. al. succeeded in the synthesis of element 100 in 1952 and named it fermium after the Italian physicist Enrico Fermi. Fm-254 was produced by neutron bombardment of Es-253.

\[ \ce{^1_0n + ^{254}_{99}Es \rightarrow ^{254}_99Fm}\]

The longest-lived isotope of fermium is Fm-257 with a half-life of 80 days.
