Transition elements of the seventh period (104 <= Z <= 112) in the periodic table are definitely relativistic elements. Even their "normal" periodic behavior has an explanation requiring direct and indirect relativistic effects plus increasing spin-orbit couplings. The chemistry of these nine (or ten, depending on conventions for group 3 composition) radioactive artificial elements forming the fourth d-series is rather limited due to their extremely scarce availability and very short lifetimes.

Abstract
Transition elements of the seventh period (104 <= Z <= 112) in the periodic table are definitely relativistic elements. Even their "normal" periodic behavior has an explanation requiring direct and indirect relativistic effects plus increasing spin-orbit couplings. The chemistry of these nine (or ten, depending on conventions for group 3 composition) radioactive artificial elements forming the fourth d-series is rather limited due to their extremely scarce availability and very short lifetimes. This perspective article gives a short outline of the most recent theorethical and experimental studies on the chemical behavior of these elements which at times appear quite ordinary but could deserve less predictable outcomes.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
