nomenclature - Why is UuX used as a symbol for unnamed …
2017年2月16日 · Until recently, the last few elements on the periodic table had the chemical symbols (now they have formal chemical symbols!): Uub, Uut, Uuq, Uup, Uuh, Uus, and Uuo Why did they have these tempor...
Why most of the atoms with fully filled outer orbits are gaseous?
2016年5月5日 · Most of the elements with fully filled outer orbits are gaseous in nature (He, Ne, Ar, Kr, Xe, Rn) with exception of Uuo (as per Wikipedia its solid). Why these fully filled outer orbit elements are always gaseous in nature? I couldn't find a any relevant links in googling. Can someone please explain? Thanks in advance.
Can metals have a net negative charge - Chemistry Stack Exchange
2015年3月16日 · However, due to relativistic effects, the superheavy noble gas ununoctium may be able to form an isolated $\ce{Uuo^-}$ anion, though it would presumably be quite reactive. Whether a compound can be made with a $\ce{Uuo^-}$ anion is not known. $\endgroup$ –
How to compute the electron configuration of an atom?
Note that the above list, if all the shells were filled, would be the electron configuration for Uuo (ununoctium), 118, the highest-numbered atom on the periodic table - so this electron configuration contains every currently known electron shell for a neutrally charged atom.
Is beryllium an alkaline earth metal? - Chemistry Stack Exchange
There is some disagreement in usage among authors, but IUPAC standard nomenclature approves calling beryllium an alkaline earth metal, as explained on page 51 of IUPAC's last Red Book.
