Question

How many neutrons are found in an isotope of F (Flourine)?

Answer 1

For `""^19F` there are 10 neutrons......

Explanation:

The `""^19F` is almost 100% abundant. Because in each fluorine nucleus, there are necessarily `"9 protons"`, why necessarily?, there must be 10 neutrons, neutral massive particles, in the fluorine nucleus.

Note that `""^19F` is 100% spin active `("I=1/2")`, it can be regularly used in `"NMR spectroscopy"`. Because fluorine chemistry is a trifle hazardous, this spectroscopy is not as well developed as that of `""^1H` or `""^13C`.
