The noble gas notation starts for elements after helium. Helium has no noble gas notation. Its electronic configuration is 1s2
h27
it's an up arrow and down arrow next to each other, beneath that it says 1s2.
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.
