A Stable Form Of Plutonium Discovered

A new compound of plutonium (Pu) with an unexpected, pentavalent oxidation state — Pu (V) has been discovered by scientists.
The new compound is solid and stable, and may represent a transient phase in radioactive waste repositories.
They figured it as Pu (V), pentavalent plutonium, a never-observed-before form of the element.
Plutonium is an unstable element and is tricky to transport, store and dispose of, but the find could lead to new ways to tackle those problems.
