Osmium
This electron configuration is for osmium (Os).
The element cerium has a single electron in the 4f orbital. Its electron configuration is [Xe] 4f1 5d1 6s2.

None. Barium is in group 2. the electronic configuration is [Xe] 6s2.
There are two possible 'noble gas' configurations:2 8 18 32 18 8 for Bi3-, or in shorthand configuration [Xe] 4f14, 5d10, 6s2 6p6and2 8 18 32 18 0 for Bi5+, or in shorthand configuration [Xe] 4f14, 5d10, 6s0 6p0Bismuth (as metaloid atom) in elemental notation: [Xe] 4f14, 5d10, 6s2 6p3
This electron configuration is for osmium (Os).
Neodymium is: [Xe] 6s2 4f4.
Here is the shortened version of the electron configuration of neodymium: [Xe] 4f4 6s2
[Xe]4f4
Europium
Osmium
Barium: [Xe]6s2
Element Os
It is [Xe54] 6s2 4f4
that would not be an element itself, but a compound containing a few different elements: xenon, sulfur, and one undiscovered element ("F" does not currently exist)
the element is tungsten with the electronic configuration Xe 4f14 5d4 6s2
It's not barium. [Xe] 6s2 is barium. But [Xe] 6s2 4f14 5d10 (or 4f14 5d10 6s2 - it doesn't matter which way round) is Hg (mercury).
