The ground state electron configuration of the hydrogen atom is 1s1, and for helium it is 1s2.
There is none because there is no noble gas above Helium
there is no shorthand configuration for helium. its electron configuration is 1s2
The electron configuration of helium is 1s2.
The electron configuration of helium is 1s2; two electrons on the first (and the single) electron shell.

Electron configuration of helium: 1s2
The electron configuration of helium is: [Xe] 4f15d16s2.
there is no shorthand configuration for helium. its electron configuration is 1s2
The electron configuration of helium is 1s2.
The electron configuration of helium is 1s2; two electrons on the first (and the single) electron shell.
The electron configuration of beryllium is written as [He] 2s2. This means that it has 2s2 electrons above the configuration of Helium.
1s2 Or, He(2) i.e., Helium has only two electrons and it is a completely filled first shell making it the simplest noble gas.
Hydrogen and helium have different valence electron configurations. Hydrogen has one valence electron, and helium has two valence electrons. However, hydrogen does typically form covalent bonds in which it shares an electron, and thereby gains an effective electron configuration of two, like helium. Hydrogen also can form the H+ ion which has no electrons.
Helium has the electron configuration 1s2
Helium is at the end of row 1 in the periodic table 1s2
