"Structural parameters and unit cell dimensions for the tetragonal actinide tetrachlorides(Th, Pa, U, and Np) and tetrabromides (Th and Pa)".

Rare earth and actinide polyhydrides may also have highish transition temperatures, for example, ThH10 with Tc 241 K.

In the periodic table, meitnerium is a d-block transactinide element.

The actinide or actinoid (IUPAC nomenclature) series encompasses the 15 metallic chemical elements.

Einsteinium(III) oxide is an oxide of the synthetic actinide einsteinium which has the molecular formula Es2O3.

In the periodic table, it is a d-block transactinide element.

In the periodic table of the elements, it is a transactinide element in the p-block.

5f electron to 6d, as is true also for the very late actinides: thus einsteinium, fermium, mendelevium, and nobelium were expected to be divalent metals.

Transactinide elements in the periodic table Z ≥ 104 (Rf) Superheavy elements, also known as transactinide elements, transactinides, or super-heavy elements.

actinides are f-block elements, corresponding to the filling of the 5f electron shell; lawrencium, a d-block element, is also generally considered an actinide.
