Actinide

Lanthanides and Actinides

The actinide 5f shell therefore often actively participates in chemical bonding, as is reflected by the higher valences of the early actinide elements ...

Electronic and Magnetic Properties of the Actinides

The reasons for this is that spin-orbit coupling plays a more important part in actinide chemistry as the 5forbitalsand their electrons are not so'core-like'as the 4f, ...

Uncovering the Secrets of Actinides

According to nuclear chemist Ken Moody, new measuring techniques and instruments, along with improved understanding of actinide chemistry, warrant revisiting test data that are decades old.

Actinide Ground-State Properties Theoretical predictions

F or nearly fifty years, the actinides defied the efforts of solid-state theorists to understand their properties. These metals are among the most complex of the long-lived elements, and in the solid state, they display some of the most unusual behaviors of any series in the periodic table.
