Octet rule: The concept that compounds containing carbon, nitrogen, oxygen, and fluorine are more stable if these atoms haveeight valence electrons. When one of these atoms has less than eight valence electrons it has an open octet. ... Every carbon, nitrogen, oxygen, and fluorine atom in t...
have been observed among the population. The development of endemic fluorosis is caused by an insufficient level of fluorine in drinking water; a direct relationship has been discovered between the concentration of fluorine in water and the frequency and severity of tooth decay. The fluorine in drin...
(H), log P, and aqueous solubility) of fluoroalkyl-substituted heterocyclic amines were profiled to facilitate the amines’ rational application in medicinal biochemistry study. The features of fluorine-containing substances had been when compared with those for the corresponding parent non-...
Within a period, elements with lower atomic numbers have lower ionization energy because the valance electrons are in higher principal energy levels. Is the statement true or false? It takes more energy to add an electron to fluorine than to oxygen because th...
Oxygen is also oxidized by platinum hexafluoride, where the platinum (in a high oxidation state) rather than the fluorine is the oxidizing agent, see https://en.wikipedia.org/wiki/Platinum_hexafluoride. The reaction is represented as O2+PtF6⟶O2+PtF6−.O2+PtF6⟶O2+PtF6−. This react...
How many neutrons does element X have if its atomic number is 43 and its mass number is 161?How to use a balance to find the mass of an object? Explain.Given that fluorine has an atomic number of 9, how are electrons placed into...
