Fluorine is highly reactive and the most electronegative element in the periodic table.
Fluorine periodic table. Grease must be avoided because of the fire hazard. Chemical element in the periodic table of elements.

Fluorine may be recovered with difficulty as a highly reactive and corrosive pale yellow gas by electrolysis of hot molten mixtures 12 of potassium fluoride kf and hydrogen fluoride hf.
Until world war ii there was no commercial production of elemental fluorine. Images c murray robertson 1999 2011 text c the royal society of chemistry 1999 2011 welcome to a visual interpretation of the table of elements the most striking version of the periodic table on the web. The presence of sodium fluoride in drinking water at the level of 2 ppm may cause mottled enamel in teeth skeletal fluorosis and may be associated with cancer and other diseases. The electrolyte is corrosive so is the product.
It is a pale yellow corrosive gas which reacts with most organic and inorganic substances. It is difficult to store as it reacts with most materials but steel and monel metal containers may be used as the metal surfaces deactivate through the formation of unreactive surface fluorides. However topically applied fluoride toothpaste dental rinses may help reduce the incidence of dental caries. Finely divided metals glass ceramics carbon and even water burn in fluorine with a bright flame.
The chemical symbol for fluorine is f. It has 9 protons and 9 electrons in the atomic structure. Since pure fluorine is violently explosively dangerous and extremely difficult to store this was my best fluorine sample for a long time see below for some real elemental fluorine. Ptfe tape is also a curious demonstration of the power of convention.
Fluorine is used to produce many chemicals including several high temperature plastics. Several early experiments with fluorine caused serious health hazards to the scientist. It was discovered by andre marie ampere in 1810. Fluorine is a 9.
However in 1810.
