The difference in the naming conventions for metallic and non-metallic ions appears to be a large part of the reason for the confusion surrounding the terms “fluorine” and “fluoride”. Another convention is that the term “fluorides” is used for compounds which contain fluorine, regardless of...
Are you confused about thedifference between fluoride and fluorineor simply want to know what fluoride is? Here's the answer to thiscommon chemistry question. Key Takeaways: What Is Fluoride? Fluoride is the name given to the negatively-charged ion of the fluorine atom (F). A fluoride may ...

Thus, it is not only that fluoride consumption has adverse health effects and reputedly makes people easier to control (as the Nazi’s believed), but the very spiritual essence of who we are, our consciousness, can be hindered from manifesting in our lives. Within our consciousnes...
There was a double increase in the fluorine content in soils over 50 years [11]. Long-term exposure to fluoride exceeding its limit value (>1.5 mg·L) was found to exert a detrimental effect on plants [12]. Fluoride compounds in soil are located mainly in the humus level, and its ...
Fluorine is a highly electronegative element belonging to the halogen group, which has the highest reactivity in the periodic table. It is one of the most abundant elements in the earth’s crust, as it forms part of various minerals mainly from volcanic origin. For this reason, regions with ...
Fluorine has a higher electronegativity, and therefore the shared electron has a higher probability that it will be closer to fluorine than hydrogen at any one time. This makes the hydrogen slightly positively charged, and the fluorine atom slightly negatively charged. There is still an overall ...
difference in electronegativity between the atoms of hydrogen and fluorine with respect to carbon. Depending on the processing conditions, PVDF exhibits several different crystalline phases (α,β,γ,δ). The β phase of PVDF is the phase that exhibits the best ferroelectric and piezoelectric ...
difference between nearby neighborhoods. At the time, children in rural China had very little exposure to fluoridated dental products [85]. The local water-fluoride concentration can then serve as a feasible and appropriate exposure parameter, and some studies emphasized that the children were born ...
Fluorine is also used in the production of hydrofluorocarbons refrigerants. Metspar grade fluorite is added to molten cast iron and steel to lower the melt temperature and viscosity, and to remove sulfur and phosphorous, fluorosilicate is formed from HF and is used for water fluoridation for ...
