Scientists made discoveries about the properties of promethium by successfully characterizing chemical complexities in solution for the first time since its discovery.
A team of scientists conducted a study based on this rare Earth element discovered 80 years ago at Oak Ridge National Laboratory . They made discoveries about the properties of promethium by successfully characterizing chemical complexities in solution for the first time since its discovery.
“The whole idea was to explore this very rare element to gain new knowledge,” stated Alex Ivanov, an ORNL scientist and co-leader of the research. “Once we realized it was discovered at this national lab and the place where we work, we felt an obligation to conduct this research to uphold the ORNL legacy.”
“Because it has no stable isotopes, promethium was the last lanthanide to be discovered and has been the most difficult to study,” said Ilja Popovs, who co-led the research. that most rare earth elements are lanthanides, elements from 57 — lanthanum — to 71 — lutetium — on the periodic table. They have similar chemical properties but differ in size.
Using X-ray absorption spectroscopy at Brookhaven National Laboratory’s National Synchrotron Light Source II, they determined the chemical bond lengths and properties of promethium.
