Subrnit … 1 Answers. Fluorine is a chemical element with atomic number 9 which means there are 9 protons in its nucleus.Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z.The total electrical charge of the nucleus is therefore +Ze, where e (elementary charge) equals to 1,602 x 10-19 coulombs. US. Most theoretical models fail to reproduce this observed feature, known as the “oxygen anomaly,” predicting instead that 2 6 O or even 2 8 O should be bound. Only fluorine-19 is stable and naturally occurring; therefore, fluorine is a monoisotopic and mononuclidic element, and only artificially produced fluorine isotopes have mass numbers other than 19. The two decay modes do not happen equally frequently however; 96.86% of the decays are by beta plus (positron) emission and 3.14% by electron capture. [2] The half-life of 26mF is 2.2(1) milliseconds; it decays mainly to the ground state of 26F or (rarely, via beta-minus decay) to one of high excited states of 26Ne with delayed neutron emission.[2]. What is the name of this isotope? Because the only ion it can make is -1, there are 10 electrons.
