It is part of the Group 7 on the periodic table of elements. What is the mass number of a fluorine atom with 8 neutrons? 5. Classified as a halogen, Fluorine is a gas at room temperature. Atomic mass =number of protons +number of neutrons=9+10=19 If we add 1 proton, then atomic number is going to be 10, and it would be Neon, because number protons define atomic number and so type of element. i think there would be: an atomic number of 17, there would be 17 protons, and there would be 18 neutrons. 19f1. For zinc, the atomic weight is 65.39, so the mass number is closest to 65. what is the atomic number of this atom? Number of Neutrons: 10 The electronic configuration is: 2, 7. 19F1-A. (To achieve octet state). Other questions on the subject: Biology. Biology, 21.06.2019 15:00, lilyplant4289. Fluorine is a monoisotopic element and its atomic weight is determined solely by its isotope 19 F. The Commission last revised the standard atomic weight of fluorine in 2013 based on the latest Atomic Mass Evaluation by IUPAP. Fluorine is less common in stars than on Earth, where it is the 13th most frequently found element in the crust. Fluorine (9 F) has 17 known isotopes, with atomic masses ranging from 14 F to 31 F (with the exception of 30 F), and two isomers (18m F and 26m F). science Most widespread minerals containing Fluorine; This list of minerals containing Fluorine is built from the mindat.org locality database. It has an atomic number of 9, meaning that it consists of 9 protons and 9 electrons. Atomic number(Z): Number of protons(or) Number of electrons present in the nucleus of an atom. What is the mass # of a fluorine atom with 8 neutrons? There are two naturally occuring "Isotopes" of Fluorine. Expert answered|Score 1|emdjay23|Points 145886| User: Matter is anything that A. has only one physical state. Fluorine (F) is the first element in the Halogen group (group 17) in the periodic table. Neon, atomic number 10 B. Boron, atomic number 5 C. Carbon, atomic number 6 D. Fluorine, atomic number 9 Weegy: Neon, atomic number 10, is a stable element. Fluorine atoms have 9 electrons and the shell structure is 2.7. The atomic number of fluorine (F) is 9.Fluorine is the chemical element with symbol F and atomic number 9. 2p5 and the term symbol is 2P3/2. The atomic mass is different than the atomic number, and the number of neutrons is the difference between the atomic mass and the atomic number.
