So, this is kind of simple.
Remember to follow through the periods on the Periodic Table to help you out with the numbers prior to the shells.
Ba is going to have all of Xe's electron configurations, and it moves down to the 6th period stopping at the s shell with 2 core electrons, meaning:
[Xe]6s^2
:] Best of luck to ya!
The element with an outermost electron configuration of 6s2 is Barium (Ba). It is classified as an alkaline earth metal on the periodic table.
All alkaline earth metals have electron configurations ending in s2; 6s2 would be the alkaline earth metal in period 6 of the PTE, which is barium.
The oxidation number of Ba in Ba²⁺ is +2. This is because in ionic compounds, like BaCl₂ where Ba²⁺ is formed, the atom loses electrons to achieve a stable electron configuration, resulting in a positive oxidation state.
The electron configuration for oxygen is [He]2s2.2p4.The electron configuration for sulfur is [Ne]3s2.3p4.
Long-hand version: 1s^2 2s^2 2p^1 Short-hand version: [He] 2s^2 2p^1 Note: The "^" symbol means the the following number is in the form of a superscript.
I assume you mean the Nobel gas electron configuration abbreviation for barium.[Ne] 6s2=======

There is no noble gas with the same electronic configuration as the element barium (Ba). But Ba2+ ion and the noble gas xenon (Xe) will have the same number of electrons (54 electrons each).
Two electrons
The oxidation number of Ba in Ba²⁺ is +2. This is because in ionic compounds, like BaCl₂ where Ba²⁺ is formed, the atom loses electrons to achieve a stable electron configuration, resulting in a positive oxidation state.
The electron configuration for oxygen is [He]2s2.2p4.The electron configuration for sulfur is [Ne]3s2.3p4.
The atom with an electron configuration ending in 5s2 is Barium (Ba), a chemical element with atomic number 56. In its ground state, Barium has two electrons in the 5s orbital.
A cation has a depleted electron configuration.
The electron configuration for beryllium, Be, is 1s22s2.
