Electron configuration of helium: 1s2
The noble gas notation of carbon is [He]2s^2 2p^2, where [He] represents the electron configuration of helium. This notation indicates that carbon has a total of 6 electrons, with 2 in the 2s orbital and 4 in the 2p orbital.
The orbital notation for thallium is [Xe}4f14.5d10.6s2.6p1.
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.

An unoccupied orbital is represented by an empty box in orbital notation. It does not have any electrons present in it but is available to accept electrons if needed.
The orbital notation for vanadium is 1s2 2s2 2p6 3s2 3p6 4s2 3d3.
The element with this orbital notation is nickel (Ni), a transition metal.
The orbital notation for oxygen is 1s^2 2s^2 2p^4. This indicates that oxygen has two electrons in the 1s orbital, two electrons in the 2s orbital, and four electrons in the 2p orbital.
[Rn]7s2
The electron configuration of helium is 1s2. This means that there are two electrons in the 1s orbital in helium.s stands for the orbital in which the electrons are present
