The noble gas electron configuration for barium is [Xe] 6s2.
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.
The electron configuration of helium is 1s2.
Full electron configuration: 1s22s22p63s23p64s23d104p65s24d105p66s24f10 Noble Gas configuration: [Xe]6s24f10
The electron configuration of strontium is 1s22s22p63s23p63d104s24p65s2.
The condensed ground state electron configuration for Barium is [Xe] 6s^2. This indicates that Barium has a full inner electron shell (represented by the noble gas configuration of Xenon) and two electrons in the outermost 6s orbital.
The electron configuration for neutral Barium is [Xe] 6s2. Barium plus 2 means it has lost 2 electrons, so the electron configuration for Barium plus 2 would be [Xe].
Barium has 2 electrons in its outermost shell. To achieve a noble gas electron configuration similar to xenon, which has 8 electrons in its outermost shell, barium would need to give up 2 electrons. This would leave barium with a full outer shell and a stable electron configuration.
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 element with an outermost electron configuration of 6s2 is Barium (Ba). It is classified as an alkaline earth metal on the periodic table.
The noble gas electron configuration for barium is [Xe] 6s2.
A barium atom attains a stable electron configuration when it bonds with a halogen atom, such as chlorine, by transferring one of its valence electrons to achieve a full outer shell. This results in the formation of an ionic bond between the two atoms.
The full electron configuration for tungsten is Xe 4f14 5d4 6s2.
Two electrons
I assume you mean the Nobel gas electron configuration abbreviation for barium.[Ne] 6s2=======
This electron configuration is for osmium (Os).
When barium forms its most common ion, it loses two electrons to achieve a full outer shell configuration, resulting in a 2+ ion (Ba^2+). This ion has a stable electron configuration similar to that of a noble gas, which is energetically favorable.
