Wiki: Fluorine - upcScavenger

Fluorine atoms have nine electrons, one fewer than neon, and electron configuration 1s 2 2s 2 2p 5: two electrons in a filled inner shell and seven in an outer shell requiring one more to be filled.The outer electrons are ineffective at nuclear Shielding effect, and experience a high effective nuclear charge of 9 − 2 = 7; this affects the atom''s physical properties.

Sodium fluoride | NaF - PubChem

Sodium Fluoride is an inorganic salt of fluoride used topically or in municipal water fluoridation systems to prevent dental caries. Fluoride appears to bind to calcium ions in the hydroxyapatite of surface tooth enamel, preventing corrosion of tooth enamel by acids. This agent may also inhibit acid production by commensal oral bacteria. (NCI04)
