Prolonged exposure to the skin and eyes can cause burns and irritation.

There are 118 elements on periodic table The number of protons in an element gives the atomic number of the element In 2016 four more elements were added into the periodic table An element refers to a substance made of atoms of the same kind.

F-containing compounds are effective markers in magnetic resonance imaging applications to detect any abnormality in the body. How Many Elements Are There The periodic table.

Its use in absorption dating aids in detecting the amount of time an object has been lying underground such as ancient fossils. If the ion has a 1- charge (simply written with a minus superscript), then there are more electrons than the number of protons.

Fluorine doped tin oxide coated glass slides find application in the manufacture of optic fibers and electronics.

Lithium-fluorine batteries are useful for their higher durability.

Polymers of F-containing monomers added to resin paints and coatings are applied on surfaces of steel plates, pots, kettles, and some heat-resistant machine parts.

Rubbers with high fluorine content have a greater strength and resistance to wear and tear that make them effective as sealing components in engines of aircrafts, cars, and rockets.

Fluorine is the most important ingredient in toothpastes and mouthwashes as it helps in removing dental plaques and preventing cavity formation.It condenses into a bright yellow liquid that is used as a cryogenic agent. The relative atomic mass is an average of the atomic masses of all the different isotopes in a sample, with each isotopes contribution to the average determined by how big a fraction of the sample it makes up.The diatomic gas is added to poly(tetrafluoroethene) and high-temperature plastics required in the making of cable insulations, water bottles, plumber’s tape, frying pans, and water-proof fabric membranes for shoes and clothing.It is useful in the preparation of uranium hexafluoride to separate uranium isotopes in nuclear power plants.Fluorine Atomic Structure (Bohr Model Diagram) What is it Commonly Used for
