Fluorine (F): Properties & Uses – StudiousGuy
Web18 feb. 2011 · Wiki User. ∙ 2011-02-18 22:51:47. Study now. See answer (1) Copy. NaF is an ionic compound consisting of a sodium ion (Na+) with a plus one charge and a fluoride ion (F-) with a minus one charge ... WebIn its ionic form, fluoride (F-), it essential in the diet, but only in small doses. It strengthens bones and teeth by becoming incorporated into the hydroxyapatite crystals, [Ca 3 (PO 4 ) 2 ] 3 · Ca(OH) 2 , of bone and enamel, converting some of it to the even harder (and more acid-resistant) form of fluorapatite, [Ca 3 (PO 4 ) 2 ] 3 · CaF 2 . Web5 apr. 2024 · In other words, the Potassium atom (K) loses 1 electron and the Fluorine atom (F) gains 1 electron. Due to this, Potassium becomes a positive ion (K +) and Fluorine becomes a negative ion (F –). Now because of the positive charge of Potassium ion and negative charge of Fluorine ion, the electrostatic force of attraction is produced … simplygacha
