Actinide concept: Origin, Acceptance & Overview

In nuclear chemistry, the actinide concept (also known as the actinide hypothesis) proposed that the actinides form a second inner transition series homologous to the lanthanides. Its origins stem from observation of lanthanide-like properties in transuranic elements in contrast to the distinct complex chemistry of previously known actinides. Glenn…
