[Ar] 4s2 3d7
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 starts for elements after helium. Helium has no noble gas notation. Its electronic configuration is 1s2
Co is cobalt and is not a noble gas. Cobalt is a transition metal. Its electron configuration is [Ar]3d74s2.
The noble gas notation for xenon is [Kr] 5s2 4d10 5p6.
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 notation for Berkelium (Bk) is [Rn] 5f^9 7s^2.
The noble gas notation for carbon uses neon as the previous noble gas. Carbon ([He] 2s^2 2p^2) can be written in noble gas notation as [He] 2s^2 2p^2.

The noble gas notation for germanium is [Ar] 3d¹⁰ 4s² 4p².
No, the noble gas notation for sulfur is [Ne] 3s2 3p4. This notation represents the electron configuration of sulfur using the nearest noble gas, which in this case is neon.
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.
