abbreviated electron configuration = e.c.
Beryllium electron configuration is [He]2s2.
The electron configuration of rutherfordium is [Rn]5f14.6d2.7s2.
The electron configuration for germanium is [Ar]3d10.4s2.4p2.
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).
[Kr]4d105s25p6
Barium (56)
The electron configuration of barium is [Xe]6s2.Barium has six electron shells with 2, 8, 18, 18, 8, 2 electrons.
[Xe]6s^2
Two electrons
I assume you mean the Nobel gas electron configuration abbreviation for barium.[Ne] 6s2=======
This electron configuration is for osmium (Os).
two chlorine atoms
Two electrons.
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.
Because by losing two electrons from the neutral atoms, a barium ion acquires a noble gas electron configuration.
barium has a 2+ chage so u would add 2 electron to take away that chage. 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p6
