[He] 2s1
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].
[He] 2s1
The outer shell contains 1 electron, ns1 Li [He] 2s1 K [Ar]4s1

The electron configuration is the number of electrons in each energy level of an element. The electron configuration of Li is, 1s2 2s1. The electron configuration of F is, 1s2 2s2 2p5.
Lithium (Li) has the electron configuration 1s2 2s1.
The electron configuration and noble gas core for Li+ is that of He: Li+: (1s2, 2s0)
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
[He] 2s1
Lithium electron configuration: 1s2 2s1, or in shorthand: [He] 2s1 Thus in LiF the Li cation (Li missing one electron to get its nobel gas configuration of He) it is Li+: 1s2 2s0, or in shorthand: [He] 2s0, This ion does NOT have 8 (octet) electrons, although it has a nobel gas configuration of He: 1s2.
The outer shell contains 1 electron, ns1 Li [He] 2s1 K [Ar]4s1
