flourine from periodic time table?

Question

if u can answer any or all of these questions about the element flourine fromt the periodic time table than that would be very helpful, thanks.
is there any obscure ways that this element is used?
Is there any form of this element that people eat?
Are there any forms of this element that are dangerous for people to eat?
Can this element be lethal?
and any other information that might be useful or interesting about flourine, thanks!

Answer 1

Fluorine has relatively few applications as a free element, largely because it is so active. Compounds of fluorine find more uses, however. For example, sodium fluoride (NaF), calcium fluoride (CaF2), and stannous fluoride (SnF2) are all used to help reduce tooth decay. They are included in "fluoridated" toothpaste and are added to the public water supply by some cities and other municipalities. Fluorides are incorporated into the structure of growing teeth and make those teeth stronger and more resistant to decay.

Fluorine was once widely used also in the production of chlorofluorocarbons (CFCs). These compounds were discovered in the late 1920s by the American chemical engineer Thomas Midgley, Jr. They have properties that make them highly desirable for a number of commercial and industrial applications, such as cooling and refrigeration systems, cleaning agents, aerosol sprays, and specialized polymers. The production of CFCs grew from about 1 million kilograms (2 million pounds) in 1935 to more than 700 million kilograms (1.5 billion pounds) in 1985.

Beginning in the early 1980s, however, research suggested that CFCs contribute to the destruction of the ozone layer, a thin layer of the stratosphere rich in ozone (O3). The ozone layer is critical to the survival of life on Earth because it absorbs ultraviolet radiation that would otherwise cause injuries and deaths. For this reason, the production and use of CFCs have been essentially banned in most parts of the world.

Another well-known use of fluorine is in the manufacture of Teflon, a widely popular non-stick plastic. Teflon is the trade name for polytetrafluorethylene, or PTFE. The material is now used in a host of products ranging from kitchen cookware to baking sprays to stain repellents used for fabrics and textiles.

Health Issues

Fluorine gas is one of the most toxic gases known to humans. Inhaled in even small amounts, it causes severe irritation to the respiratory system and, in larger doses, it can cause death. The highest recommended exposure to fluorine is one part per million of air over an eight-hour period. Fortunately, few people are likely to encounter elementary fluorine in their daily lives.

Answer 2

Think about an instance where we add some objects (electrons) to a bag which is already filled up with objects (fluorine atom).You ll see that it is difficult to add more objects due to lack of space.With the same idea, we can say that fluorine atom has a low affinity to receive an electron because it has a small size .So repulsion given to incoming electron is high .While in case of chlorine atom, it ll easily recieve an electron because it has a large size compared to fluorine . Therefore electron affinity of chlorine is greater than that of fluorine.

Answer 3

The easiest thing to do is look it up on the internet. There are numerous sites.

Quickly said, Fluorine is contained in dental products as it prevents tooth decay. It is included in many powerful anti-cancer pharmaceuticals and agrochemicals. By the same token, it can be very toxic. (That's why it can kill cancer cells).

Answer 4

i'll tell u 2 things:
1- It's a toxic gas , so could be used as poisounous
2-we use fluroid compounds in toothpastes
