The ground state electron configuration of hydrogen is 1s^1, meaning it has one electron in the 1s orbital. Helium in its ground state has an electron configuration of 1s^2, indicating it has two electrons in the 1s orbital. So, the main difference is that hydrogen has one electron in its outer shell while helium has two electrons in its outer shell.
The ground state electron configuration of a hydrated atom, such as a hydrated helium ion (He⁺), typically involves the addition of water molecules, which can influence the atom's behavior and interactions. In contrast, a neutral helium atom has a ground state electron configuration of 1s², with two electrons in the 1s orbital. When hydrated, the interactions with water molecules can lead to changes in energy levels and electron distribution, but the intrinsic electron configuration of helium remains the same. Thus, while the fundamental configuration of helium is unchanged, the environment in which it exists alters its properties and behaviors.
There is none because there is no noble gas above 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.
The electron configuration for nitrogen is written as 1s2 2s2 2p3.

Noble gases, like helium, neon, and argon, have no unpaired electrons in their ground state electron configuration. This means that all of their electrons are paired up in orbitals.

Electron configuration of helium: 1s2
Lithium ion (Li+) and beryllium ion (Be2+) have the same electron configuration as helium because they both have filled electron shells.
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.
The electron configuration for nitrogen is written as 1s2 2s2 2p3.
The electron configuration of helium is 1s2.
The electron configuration of helium is 1s2; two electrons on the first (and the single) electron shell.
He 2s1 refers to a specific electronic configuration of a helium atom, where "He" stands for helium, and "2s1" indicates that there is one electron in the 2s orbital. In its ground state, helium has the electronic configuration of 1s², meaning both of its electrons occupy the 1s orbital. The notation "2s1" suggests that one electron has been promoted to the 2s orbital, which can occur in excited states. This configuration is important in understanding helium's chemical properties and behavior in various physical contexts.
The electron configuration of beryllium is written as [He] 2s2. This means that it has 2s2 electrons above the configuration of Helium.
