Lithium atom

A lithium atom is an atom of the chemical element lithium. 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. Similarly to the case of the helium atom, a closed-form solution to the Schrödinger equation for the lithium atom has not been found. However, various approximations, such as the Hartree–Fock method, can be used to estimate the ground state energy and wavefunction of the atom. The quantum defect is a value that describes the deviation from hydrogenic energy levels.

gollark: > datetimeObviously I already stored that.> can revisions branch like in git?Nope.> tbh why not directly use git?- can't really store/manage structured metadata well- probably annoying to interface with- would require filesystem storage instead of my neat SQLite database thing- apioforms- merge conflicts- likely to end up as a somewhat leaky abstraction
gollark: I'll just leave that constantly as `()`.
gollark: Currently my thing™ just stores the size, which is a vaguely useful metric.
