Lithium atom. A lithium atom is an atom of the chemical element lithium.Stable lithium is composed of three electrons bound by the electromagnetic force to a nucleus containing three protons along with either three or four neutrons, depending on the isotope, held together by the strong force.

Lithium metal is isolated electrolytically from a mixture of lithium chloride and potassium chloride. The nucleus of the lithium atom verges on instability, since the two stable lithium isotopes found in nature have among the lowest binding energies per nucleon of all stable nuclides.
The picture shows a single electron shell for all (3) electrons for lithium-7. Would (2) electron shells make more sense? Or to be more accurate, instead a draw a picture of lithium-7 atom displayed in the quantum model. Goslackware 17:33, 4 October 2023 (UTC)
Naturally occurring lithium (3 Li) is composed of two stable isotopes, lithium-6 (6 Li) and lithium-7 (7 Li), with the latter being far more abundant on Earth. Both of the natural isotopes have an unexpectedly low nuclear binding energy per nucleon (5 332.3312(3) keV for 6 Li and 5 606.4401(6) keV for 7 Li) when compared with the adjacent lighter and heavier elements, helium (7 073.9156(4) keV ...

The overlaps get quite close at the point where the d-orbitals enter the picture, [50] and the order can shift slightly with atomic number [51] and atomic charge. [52] [h] Starting from the simplest atom, this lets us build up the periodic table one at a time in order of atomic number, by considering the cases of single atoms.
