[Ar]3d74s2
The noble gas configuration for Sr (strontium) is [Kr]5s2
The noble gas configuration for cobalt (Co), which has an atomic number of 27, is [Ar] 3d^7 4s^2. This notation indicates that cobalt has the electron configuration similar to that of argon, followed by seven electrons in the 3d subshell and two electrons in the 4s subshell.
The noble gas configuration for Sr (strontium) is [Kr]5s2
The electron configuration and noble gas core for Li+ is that of He: Li+: (1s2, 2s0)
The noble gas electron configuration of radon is [Xe]4f145d106s26p6.
The noble gas configuration for Sr (strontium) is [Kr]5s2
The noble gas configuration for Sr (strontium) is [Kr]5s2
Co is cobalt and is not a noble gas. Cobalt is a transition metal. Its electron configuration is [Ar]3d74s2.
The correct noble gas configuration for Li is neon (1s^2 2s^1).
The electron configuration and noble gas core for Li+ is that of He: Li+: (1s2, 2s0)
[He] 2s1
The noble gas core for fluorine is neon. So the electron configuration for fluorine with a noble gas core is [Ne] 3s^2 3p^5.
The noble gas electron configuration of radon is [Xe]4f145d106s26p6.
The "Noble gas electron configuration," or the condensed electron configuration, for F is [He] 2s2 3p5.
It is [Ar] 3d10 4s2 4p4
The noble gas configuration of oxygen (O) is [He] 2s^2 2p^4, where [He] represents the electron configuration of the nearest noble gas, helium.
Only group 18 elements have noble gas configuration. All other elements lack a noble gas electronic configuration.
