Fluorine  F

Fluorine is a chemical element with the symbol F and atimic number 9. It is the lightest halogen and exists at standard conditions as a highly toxic, pale yellow diatomic gas. As the most electronegative element, it is extremly reactive, as it reacts with all other elements except for argon neon and helium etc 

Atomic number              9 

Atimic mass.                   18.998403 g.mol-1

Fluorine is an unvalent poisonous gaseous halogen, it pale yellow green and it is most chemically reactive and electronegative of all the elements. Fluorine readily forms compounds with mist other element even with noble gases krypton, xenon and radon. It is so reactive that glass, metals and even water, as well as other substances burn with bright flame in a jet of fluorine gas 

In aqueous solution fluorune commonly occours as the fluoride ion F- fluoride are compounds that combine fluoride with some
