What is the position of fluorine ion in periodic table?
Fluorine (F) is the first element in the Halogen group (group 17) in the periodic table. Its atomic number is 9 and its atomic weight is 19, and it’s a gas at room temperature. It is the most electronegative element, given that it is the top element in the Halogen Group, and therefore is very reactive.

How do you isolate fluorine?
Henri Moissan, a French chemist, finally isolated fluorine in 1886 — after being poisoned several times in his pursuit. He was awarded the Nobel Prize in 1906 for the isolating fluorine by electrolysis of dry potassium hydrogen fluoride (KHF2) and dry hydrofluoric acid.
Why fluorine and chlorine reacts with water?
The halogens are all oxidizing elements with fluorine and chlorine being the most electronegative elements in the group. Hence, the most oxidizing and as a result, both fluorine and chlorine are able to oxidize (react) with water to greater extents forming different products.
Why fluorine does not show displacement reaction in aqueous solution of chlorine?
Due to difference in electronegativity, Fluorine can displace chlorine, Bromine and iodine. But in aqueous solution, fluorine replaces oxygen in water more rapidly and hence not preferred to conduct displacement reactions of Cl,Br and I.
Why is fluorine a weak bond?
The fluorine–fluorine bond of the difluorine molecule is relatively weak when compared to the bonds of heavier dihalogen molecules. This is a result of the relatively large electron and internuclear repulsions, combined with a relatively small overlap of bonding orbitals arising due to the small size of the atoms.
What is the periodic table of fluorine?
Fluorine – Periodic Table. Fluorine is a 9. chemical element in the periodic table of elements. It has 9 protons and 9 electrons in the atomic structure. The chemical symbol for Fluorine is F.
Why is the radius of oxygen and fluorine lower than fluorine?
The higher effective nuclear charge of Oxygen and Fluorine makes these two elements draw the outermost electrons closer and lowering the radius. Indeed , you are not right (N > O > F). They all have 2 shells, but different numbers of electrons. To memorize “from left to right radius decrease, from top to bottom increase”.
What is the electron configuration and density of fluorine?
In the periodic table, the elements are listed in order of increasing atomic number Z. Electron configuration of Fluorine is [He] 2s2 2p5. Possible oxidation states are -1. Density of Fluorine is 0.00170g/cm3. Typical densities of various substances are at atmospheric pressure.
How many protons are in the nucleus of fluorine?
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.
