[He] 2s1
[He] 2s1
The electron configuration and noble gas core for Li+ is that of He: Li+: (1s2, 2s0)
Li, Be, O: the first term in the abridged electron configuration is [He]. Ca, K: the first term in the abridged electron configuration is [Ar].
Both lithium (Li) and sodium (Na) have one electron in their outermost energy level, giving them similar electronic configurations. They both have an electron configuration of [Ne] 3s¹, where [Ne] represents the electron configuration of the noble gas neon.
[He] 2s1
[He] 2s1
The element with the electron configuration 2s1 is lithium (Li). However, there is no element with the electron configuration S2d1 as "S" and "d" are not valid subshells in the electron configuration notation based on the periodic table.
Lithium (Li) has the electron configuration 1s2 2s1.
The electron configuration of lithium (Li) is 1s2 2s1, with 3 electrons distributed in the 1s and 2s orbitals. The electron configuration of fluorine (F) is 1s2 2s2 2p5, with 9 electrons distributed in the 1s, 2s, and 2p orbitals.
The configuration of the lithium ion (Li⁺) is 1s². In its neutral state, lithium has the electron configuration of 1s² 2s¹, but when it loses one electron to become Li⁺, it loses the 2s electron, leaving only the 1s electrons.

The electron configuration and noble gas core for Li+ is that of He: Li+: (1s2, 2s0)
[He] 2s1
Li, Be, O: the first term in the abridged electron configuration is [He]. Ca, K: the first term in the abridged electron configuration is [Ar].
Both lithium (Li) and sodium (Na) have one electron in their outermost energy level, giving them similar electronic configurations. They both have an electron configuration of [Ne] 3s¹, where [Ne] represents the electron configuration of the noble gas neon.
The ions of elements nitrogen (N3-), oxygen (O2-), and fluorine (F-) will have the same electron configuration as a sodium ion (Na+), which is the same as the electron configuration of the noble gas neon.
[Ne]3s1i think but I'm not sure as i haven't seen this before but i know it as 2,8,1
