A fluoride ion is
WebNov 22, 2024 · A fluoride ion is an atom with 9 protons in its nucleus, making it a fluorine atom. It is an “ion” because the number of electrons is not equal to the number of protons, which is also the reason for the “ide” suffix. More specifically, each fluoride ion has 10 electrons, giving it a net electrical charge (also known as a valence) of -1. WebMay 31, 2024 · When a fluorine atom forms the fluoride ion? If a fluorine atom gains an electron, it becomes a fluoride ion with an electric charge of -1. Is the fluoride ion bigger than a fluoride atom? Statement I: The fluoride ion has a larger radius than the fluorine atom. Statement II: The fluoride ion has 8 electrons and 9 protons.

At low doses, fluorides induce lamellar bone, and at higher doses abnormal woven bone of inferior quality. The effect of fluorides on normal and abnormal (e.g., osteoporotic) bone is therefore dose-dependent.
