氟的电子层排布形式为1S~22S~22P~5,它是所有元素中化学性质最活泼、负电性最强(=4.0)的一种元素。氟的有效离子半径等于1.33A(Wedepohl,1974),与(OH)~-(1.40A)和O~(2-)(1.40A)非常接近,因此F~-常与(OH)~-和O~(2-)发生替换而赋存在某些矿物中。到目前为止,在自然界已发现主要含氟矿物有149种(Strunz,1970),其中硅酸盐63种,卤化物34种,磷酸盐22种,其他含氟矿物30种。在火成岩中最常见的含氟矿物是云母、闪石、磷灰石以及萤石、榍石等。
Fluorine electron layer arrangement of the form 1S ~ 22S ~ 22P ~ 5, which is the most active chemical element of all the elements, the most electronegative (= 4.0) of an element. The effective ionic radius of fluorine equals 1.33A (Wedepohl, 1974), which is very close to (OH) ~ - (1.40A) and O ~ (2-) (1.40A) O ~ (2-) replaced occur in some minerals. To date, 149 major foraminiferous minerals have been found in nature (Strunz, 1970), including 63 silicates, 34 halides, 22 phosphates and 30 other fluorinated minerals. The most common fluorinated minerals in igneous rock are mica, amphibole, apatite, fluorite, gallstone and the like.
