Lithium fluoride is an inorganic compound with the chemical formula LiF. It is a colorless solid that transitions to white with decreasing crystal size. Its structure is analogous to that of sodium chloride, but it is much less soluble in water.
Representation of ionic bonding between lithium and fluorine to form lithium fluoride. Lithium has a low ionization energy and readily gives up its lone valence electron to a fluorine atom, which has a positive electron affinity and accepts the electron that was donated by the lithium atom.

Lithium fluoride is the only alkali metal halide that is poorly soluble in water, [5] and lithium hydroxide is the only alkali metal hydroxide that is not deliquescent. [5] Conversely, lithium perchlorate and other lithium salts with large anions that cannot be polarised are much more stable than the analogous compounds of the other alkali ...
Lithium compounds are also used as additives (fluxes) to foundry sand for iron casting to reduce veining. [166] Lithium (as lithium fluoride) is used as an additive to aluminium smelters (Hall–Héroult process), reducing melting temperature and increasing electrical resistance, [167] a use which accounts for 3% of production (2011).

Sodium fluoride: yellow is fluorine, purple is sodium. They are isoelectronic, but fluorine is bigger because its nuclear charge is lower. The alkali metals form monofluorides. All are soluble and have the sodium chloride (rock salt) structure, [47] Because the fluoride anion is basic, many alkali metal fluorides form bifluorides with the ...

Lewis structure of a water molecule. Lewis structures – also called Lewis dot formulas, Lewis dot structures, electron dot structures, or Lewis electron dot structures (LEDs) – are diagrams that show the bonding between atoms of a molecule, as well as the lone pairs of electrons that may exist in the molecule.
