The noble gas notation of magnesium is [Ne] 3s2. This shows that the third energy level is the highest occupied energy level and magnesium is in period 3 of the Periodic Table. Also there are two valence electrons for magnesium in the s orbital.
Magnesium: 1s2 2s2 2p6 3s2
is
[Ne] 3s2 in noble gas notation.
[Ne]3s2
The chemical symbol of magnesium is Mg.
Mg-24
Electron Configuration for Mg: 1s2 2s2 2p6 3s2 Noble Gas Notation for Mg: [Mg] 3s2
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 for Iron (Fe) is [Ar]4s2 3d6.
The noble gas notation starts for elements after helium. Helium has no noble gas notation. Its electronic configuration is 1s2
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.
