Fluorine is the lightest halogen and exists as a extremely toxic pale yellow diatomic gas at traditional conditions. Together the many electronegative element, the is very reactive: virtually all other elements, consisting of some noble gases, form compounds v fluorine.

Owing come the price of refining pure fluorine, many commercial applications use fluorine compounds, v about fifty percent of mined fluorite used in steelmaking.

Fluorine is obtained by the electrolysis the a systems of potassium hydrogendifluoride in anhydrous hydrofluoric acid.


Protons and also Neutrons in Fluorine

*
Fluorine is a chemical facet with atom number 9 which means there are 9 proton in that nucleus. Total variety of protons in the cell core is dubbed the atomic number of the atom and is given the symbol Z. The full electrical charge of the cell nucleus is thus +Ze, whereby e (elementary charge) equals to 1,602 x 10-19 coulombs.

The full number of neutrons in the cell nucleus of one atom is called the neutron number of the atom and is provided the symbol N. Neutron number plus atomic number equals atomic mass number: N+Z=A. The difference between the spirit number and also the atomic number is recognized as the neutron excess: D = N – Z = A – 2Z.

For secure elements, there is commonly a range of secure isotopes. Isotopes room nuclides that have the same atomic number and are as such the very same element, however differ in the variety of neutrons. Mass numbers of common isotopes of Fluorine are 19. 

Main isotope of Fluorine

Only one isotope of fluorine occurs naturally in abundance, the steady isotope 19F. The isotope 17F and 18F undergo β+ decay and also electron capture, lighter isotopes degeneration by proton emission, and also those heavier 보다 19F undergo β− decay (the most heavy ones with delayed neutron emission).

Fluorine-19 is written of 9 protons, 10 neutrons, and 9 electrons. Its variety is 100%; no other isotopes of fluorine exist in far-reaching quantities.

Fluorine-18 is composed of 9 protons, 9 neutrons, and also 9 electrons. The the unstable nuclides the fluorine, 18F has actually the longest half-life, 109.739 minutes. It has actually two degeneration modes, of i m sorry the key one is positron emission. Therefore 18F is a commercially important source of positrons.

Fluorine-20 is written of 9 protons, 11 neutrons, and also 9 electrons. Fluorine-20 is one of the an ext unstable isotope of fluorine. It has a half-life that 11.07 seconds and also undergoes beta decay.
