Fermium, denoted by the symbol Fm, is a synthetic element that does not exist in nature and is produced in nuclear reactors. It belongs to the actinide series and is part of the periodic table’s seventh period. Fermium is named after physicist Enrico Fermi, who played a crucial role in the development of nuclear energy. Due to its radioactive nature and limited availability, fermium’s applications are primarily confined to scientific research and the study of nuclear reactions.
Fluoride is not an element on its own but deserves mention as an anion derived from fluorine. It plays a crucial role in dental health and is commonly added to toothpaste and drinking water to prevent tooth decay. Fluoride ions interact with the enamel of teeth, forming a protective layer that makes them more resistant to acid attacks from bacteria. While essential for dental health, excessive fluoride intake can lead to dental and skeletal fluorosis, highlighting the delicate balance required for its optimal utilization.
Fluorocarbons are organic compounds consisting of carbon and fluorine atoms. These compounds often exhibit unique properties, such as high thermal stability and resistance to chemical reactions. One notable example is polytetrafluoroethylene (PTFE), commonly known as Teflon. PTFE is renowned for its nonstick properties, making it widely used in cookware. Fluorocarbons also find applications in refrigerants, lubricants, and as insulating materials due to their exceptional chemical and thermal stability.
