WebMar 1, 2011 · Curium (III) salts are isomorphous with their lanthanide analogues, and the solution chemistry of Cm (II) is similar to that of the lanthanides. The basic electronic configuration is probably [Rn]7s 2 5f 7, though some mixing of 6d and 5f orbitals is likely. WebJul 19, 2013 · Curium is the most radioactive element that can be isolated. It is so intensely radioactive that it boils water, making its chemistry difficult to study. It also glows in the dark (see right).
