The noble gas configuration for Sr (strontium) is [Kr]5s2
There is no boble gas notation for hydrogen and helium. The noble gas notation starts for elements after helium. The noble gas notation is a notation formed as a result of the electron configuration notation being used in conjunction with noble gases. The noble gas preceding the element in question is written then the electron configuration is continued from that point forward.
The noble gas notation is a notation formed as a result of the electron configuration notation being used in conjunction with noble gases. The noble gas preceding the element in question is written then the electron configuration is continued from that point forward. The notation is shorter to write and makes it easier to identify elements. The noble gas notation starts for elements after helium. For example, the electronic configuration of carbon is 1s2 2s2 2p2, whereas its noble gas notation is [He] 2s2 2p2.
The noble gas configuration for Sr (strontium) is [Kr]5s2
The noble gas notation for the electron configuration of iron (Fe) is [Ar] 3d6 4s2, where [Ar] represents the electron configuration of the noble gas argon.
I am assuming that the question is for Co2+ ion. and the answer is [Ar] 3d5 4s2
[He] 2s1

The noble gas notation starts for elements after helium. Helium has no noble gas notation. Its electronic configuration is 1s2
[Ne] 3s2 3p6
The noble gas notation for Xenon is [Kr] 4d^10 5s^2 5p^6. This notation represents the electron configuration of Xenon with the closest noble gas element, Krypton, in brackets followed by the configuration for Xenon.
