WebJan 31, 2024 · We can see the outer most shell of fluorine has 6 electrons so, have to subtract it from 8. 8 – 7 = 1 That’s why valency of fluorine is 1. Note: In general, fluorine has a stable oxidation state of -1 most of the time but it can differ in some compound like F2 and HOF where its oxidation state is 0 and +1 respectively. WebDec 15, 2024 · When forming ions, elements typically gain or lose the minimum number of electrons necessary to achieve a full octet. For example, fluorine has seven valence electrons, so it is most likely to gain one electron to form an ion with a 1- charge. We can use this method to predict the charges of ions in ionic compounds.

WebThe Aufbau principle is that the electrons present in the atom will first complete the lowest energy orbital and then gradually continue to complete the higher energy orbital. Electron configuration via Aufbau principal The atomic number of fluorine is 9, which means it … WebAnd so fluorine will be happy if it can gain 1 more electron to have a full octet of outer shell electrons. If it does, then it becomes a 1- ion: the F - ion. Similar reasoning can be applied to oxygen. The electron shell diagram shows 6 valence shell electrons. candida albicans pathogenesis
