English
Etymology
From eka- + protactinium.
Noun
eka-protactinium (uncountable)
- unbitrium (Ubt), an unsynthesized chemical element with atomic number 123.
- unquadunium (Uqu), an unsynthesized element with atomic number 141.
Usage notes
This inconsistency, between referring to element 123 versus element 141, comes from the fact the elements beyond oganesson are not known, so it is unknown what element would be placed directly below protactinium.
