What is the most recently named element?

Question

I am only interested in the name, atomic number and symbol. I don't really care about half-lifes

Answer 1

Ununquadium (symbol Uuq. Atomic number 114) is the most recently accepted element (as of 2005).
Other elements have been discovered and named since and included on a temporary basis provisional to universal acceptance. The most recent of these is ununhexium (symbol Uuh. Atomic number 116).
However, the names of all elements above atomic number 111 are systematic, and the system is still being contested. So although systematic names would logically be preferable they are accepted only provisionally at present and may change in the future.
So in reality the most recently named element which has a name which will definitely not change is roentgenium (symbol Rg. Atomic number 111).

Answer 2

Element 118 -ununoctium, Uuo-- heaviest undiscovered transuranic element at the time (lead-krypton) but he discovery was retracted for lack of conclusive evidence. Three atoms of element 118 (ununoctium, Uuo) were synthesizesed by fusing krypton-86 (8636Kr) with lead-208 (20882Pb)

Element 116-ununhexium (Uuh) is a decomposed version of 118

Answer 3

Derek, Unununium is actual factor interior the experience that this is been synthetically produced and regular. The call is an old call that became in user-friendly terms used quickly. while a clean factor is first suggested, IUPAC (international Union of organic and utilized Chemistry) themes a momentary call it fairly is predicated in user-friendly terms on the atomic kind till deliberations are accomplished to confirm on the actual call. because of the fact the latin prefix meaning "one" is "un", and that's the factor with atomic kind 111, the call given became "unununium" in 1994 while it became initially discovered. This became used till 2004, while the merely actual call for the factor, "Roentgenium", became ultimately agreed upon. persons, Who gave thumbs all the way down to 2 good 2 omit? His answer is actual! what's occurring obtainable?

Answer 4

First, I really don't count the systematic names as actual names. We can name them without actually having discovered them. However, IUPAC names the elements once they are confirmed. The last one to be named is Element 111, Roentgenium. This element was discovered in 1994 and isolated in Darmstadt, Germany.

Answer 5

Other than the "unblahiums," which I don't really consider names, darmstadtium is the most recent I know of (and I keep pretty well updated on such things).

Atomic #110, Ds
