Values of capacitors are usually specified in terms of SI prefixes of farads (F), microfarads (μF), nanofarads (nF) and picofarads (pF). [9] The millifarad (mF) is rarely used in practice; a capacitance of 4.7 mF (0.0047 F), for example, is instead written as 4 700 μF. The nanofarad (nF) is used more often in Europe than in the United States ...
Conversions between units in the metric system are defined by their prefixes (for example, 1 kilogram = 1000 grams, 1 milligram = 0.001 grams) and are thus not listed in this article. Exceptions are made if the unit is commonly known by another name (for example, 1 micron = 10 −6 metre).
At room temperature N 2 F 4 is mostly associated with only 0.7% in the form of NF 2 at 5 mmHg (670 Pa) pressure. When the temperature rises to 225 °C, it mostly dissociates with 99% in the form of NF 2. [5] In NF 2, the N–F bond length is 1.3494 Å and the angle subtended at F–N–F is 103.33°. [7]

Nitrosyl fluoride is typically produced by direct reaction of nitric oxide and fluorine, although halogenation with a perfluorinated metal salt is also possible.The compound is a highly reactive fluorinating agent that converts many metals to their fluorides, releasing nitric oxide in the process:
Phosphorus pentafluoride is a Lewis acid.This property is relevant to its ready hydrolysis. A well studied adduct is PF 5 with pyridine.With primary and secondary amines, the adducts convert readily to dimeric amido-bridged derivatives with the formula [PF 4 (NR 2)] 2.
A variety of other tetrafluoroammonium salts are known ([NF 4] + X −), as are fluoride salts of other ammonium cations ([NR 4] + F −).. In 1966, W. E. Tolberg first synthesized a five-valent nitrogen compound of nitrogen and fluorine when tetrafluoroammonium compounds, tetrafluoroammonium hexafluoroantimonate(V) [NF 4] + [SbF 6] − and tetrafluoroammonium hexafluoroarsenate(V) [NF 4 ...
