They have such short lifetimes
Scientists are uncertain about the electronic structure of the Actinides because they have short lifespans. Some of the actinides have such short half lives that it is impossible to figure out their exact chemistry.
the actinides have complex atomic structures due to the presence of inner 5f orbitals, leading to difficulties in predicting their electronic configurations accurately. Additionally, the actinides exhibit multiple oxidation states, making it challenging to determine the precise electron arrangements in different chemical environments. The influence of both relativistic effects and electron correlations further complicates the understanding of actinide electronic structures.
Uncertain, but sometime in the early 1950s when an off the shelf electronic analog computer was interfaced to an electronic digital computer.

Uncertain etiology means the cause is unknown.
yes, Nessie or "the loch ness monster" lives in irerland in a place called loch ness. hence the name. Nessie is a question many people ask. scientist have clues that lead to the existence of it but we are still uncertain. yes, Nessie or "the loch ness monster" lives in irerland in a place called loch ness. hence the name.

THE ANSWER IS UNSURE. THIS IS ONE OF MANY SYNONYMS OF UNCERTAIN.
antonym: uncertain, unsure
Uncertain Pleasures was created in 1990.
