Fluorine

My Nucleus contains nine protons and ten neutrons.

i have 17 known isotopes, but only one of them has a stable half life. It has an atomic mass of nineteen. These isotopes have half lives ranging from 109.77 minutes to less than 40 nanoseconds. .

I have nine electrons
flourine orbitals

my electron configuration is [He].2s2.2p5

i have 7 valence electrons

I am Element!

I AM FLUORINE

My Compounds
(My Friends!)
Oxygen and Hyderogen are the most common halogens(halides). examples of these compounds are:
O2F2- name: oxygen(I) fluoride, weight: 69.996, oxidation#: -1

OF2- name: oxygen (II) fluoride, weight: 53.996, Oxidation #: -1

HF- name: hydrogen(I) fluoride, weight: 20.006, oxidation #: -1

My Story

i was discovered in 1886 by Joseph Henri Moissan. i was named from the Latin word fluo, which translates to flow. i was obtained from mineral fluorite and have many uses. one of my uses is to be used as a refrigerant.

My Jobs

i have many jobs. i am used in the synthesis of organic fluorine compounds. i am also used in the manufacture of Freon (i.e. dichlorodifluoromethane, CCl2F2) which is used as a refrigerant. i am involved in the manufacture of uranium hexafluoride which is required for the separation of the isotopes of uranium in centrifuges.
