El curio es un elemento sintético bautizado en honor a Marie y Pierre Curie. Se usa como fuente de energía en misiones espaciales mediante generadores termoeléctricos de radioisótopos.

Acerca de Curio

The name curium honours Marie and Pierre Curie, and the element sits immediately beyond americium in the actinide series at atomic number 96. Its relative atomic mass is 247.0, its configuration [Rn] 5f7 6d1 7s2, and its Pauling electronegativity 1.3; the metal is solid at standard temperature and pressure. Curium is synthetic and intensely radioactive, and the heat released by its decay is substantial enough to be engineered around. That heat has been used aboard spacecraft, where radioisotope thermoelectric generators convert the thermal output of a decaying actinide into electrical power for instruments operating far from the Sun. The element has no application outside research and specialised nuclear engineering.
