PLEASE CORRECT ME IF I'M WRONG..I really need to know exactly how many of each "subatomic particle" it has. Fluorine has nine protons and nine electrons. In Uncategorized. Anyways, if you can please tell me how many of those three Fluorine 17 has and how to find them, please do so. When an atom gains an electron it gains a negative charge and becomes anion.So, we should add the same number equal to its negative chanrge to the number of electron it has when its a neutral atom. 7 Fluorine's electron configuration is: [He]2s^2\2p^5 or 1s^2\2s^2\2p^5 Therefore, its valence shell is n=2, and so it contains 2+5=7 valence electrons.

There are also tutorials on the first thirty-six elements of the periodic table. A chemist is identifying the elements present in a sample of seawater. Step 1: For the number of protons, it is equal to the atomic number. How many neutrons does Fluorine (F) have? An atom, which is the fundamental unit of an element, contains an equal number of electrons and protons. Fluorine has atomic number 9. It is an unstable element with 9 protons, 10 neutrons, and 9 electrons. This question is part of Atom Element Blocks, Bohr Models and Element Classes. Request. Share Reply. How would they be identified using isotope notation? He who owns the information, owns the world – said V.Cherchill. How many protons and electrons does fluorine have? How many protons, neutrons, and electrons does it have? The number of neutrons is calculated by subtracting the atomic number from … Share. Likewise, how many protons does fluorine have? 2 5 7 9 See answer znk znk Answer: Hydrogen has one electron Explanation: Hydrogen is the first element in the Periodic Table, so it has only one valence electron. a) 9 b) 28 c) 10 d) 19. 0. I have to do a project in Physical Science on making an atomic model for a element. 9. I have to do a model on any of the first 36 elements on the Periodic Table and I chose Fluorine. Fluorine (F) forms a fluoride ion (anion) by accepting one more electron in its valence shell. It says 9 on fluorine on the Periodic Table, so I'm wondering if that means fluorine has 9 neutrons, 9 electrons, and 9 protons. Tags: Question 3 . The symbol of Fluoride ion is F - ion . How manyelectron shells? Fluorine is halogen and is the most electronegative element among the halogens. how many valence electrons does fluorine have. The number of neutrons = the atomic mass - the atomic number (or number of protons… positive charge ⁺¹ . Fluorine has 7 . How many protons and neutrons does fluorine have?
