Edexcel C2 exam - 'Unofficial Markscheme' 10/06/2014, Why is lead a product of lead bromide electrolysis, CHEMISTRY: Reactions of halogens and halides. Chlorine is more reactive than bromine because the chlorine molecule is has fewer shells in total therefore the electronic bonding is stronger. This makes the radius (the distance from the nucleus to the outer shell) of the bromine atom larger than that of the chlorine atom.

Chlorine has more electrons so repels a reacting electron with greater force than fluorine, making it less likely to react. The bromine nucleus therefore has to attract an electron from further away, and this greater distance means the electron is attracted less strongly. Need tips :), No, I think predicted grades should still be used to make offers, Yes, I like the idea of applying to uni after I received my grades (PQA), Yes, I like the idea of receiving offers only after I receive my grades (PQO), I think there is a better option than the ones suggested (let us know in the thread! We know this by referring to the periodic table. In most cases, chlorine is more reactive than bromine. In most cases, chlorine is more reactive than bromine.

Actually, in nature, bromine exists as bromide salts instead of Br 2. Du kan give Verizon Media og vores partnere lov til at behandle dine personlige data ved at vælge 'Jeg accepterer'. Watch the video here >>, Applying to uni? The stability of completing the p orbital for fluorine is greater than for bromine which is the same as saying fluorine is more keen to obtain an electron than bromine. Bromine is less reactive than chlorine but more reactive than iodine. GCSE CHEM: Can someone explain electrolysis in simple words please? Tell us a little about yourself to get started. © Copyright The Student Room 2017 all rights reserved. This occurs because chlorine has a higher electronegativity than bromine.

You can personalise what you see on TSR. As chlorine is more reactive than bromine, chlorine will displace bromine fro a a solution of the bromide salt sodium bromide. ), Join Uni of Surrey for a Q and A on personal statements. If Chlorine is reacted with with sodium bromide solution, then the mixture will turn brown; bromine has been formed.

This is shielding. What did you accomplish during the pandemic. the tendency to gain electrons decreases on moving down the group because their atomic size increases. Chlorine is more reactive than bromine because the chlorine molecule is has fewer shells in total therefore the electronic bonding is stronger. Fluorine also has fewer electron shells than chlorine, so there are fewer electrons between the positive nucleus and the reacting electron to essentiallly block, or weaken, the electromagnetic attraction. It produces the bromide ion by taking up one electron. (Start typing, we will pick a forum for you), Taking a break or withdrawing from your course, Maths, science and technology academic help, Why is chlorine more reactive than bromide, "Explain why silver chloride is more soluble is ammonia than silver bromide", Using PCl5 as a chlorinating agent for alcohols. The three common Group 7 elements are chlorine, bromine and iodine. The bromine nucleus therefore has to attract an electron from further away, and this greater distance means the electron is attracted less strongly. When chlorine (as a gas or dissolved in water) is added to sodium bromide solution, the chlorine takes the place of the bromine. A cylinder of propane C3H8 contains 16.00kg of liquefied gas. 806 8067 22 Registered Office: International House, Queens Road, Brighton, BN1 3XE, I need help answering this question, Why is chlorine more reactive than bromide, Chlorine is in group 7 on the periodic table therefore has 7 electrons in its outershell,bromine is also in group 7 however is below chlorine and it goes up in reactivity in the periodic table. This makes the radius (the distance from the nucleus to the outer shell) of the bromine atom larger than that of the chlorine atom. Chemistry 9-1 GCSE equations and formulae, How to get an A* on A-Level Chemistry? Chemical reactivity of non metals depends on their tendency to gain electrons. Fluorine is a smaller than bromine therefore the cloud of electron density surrounding the nucleus is more compact. Du kan ændre dine valg når som helst i Dine kontrolfunktioner til beskyttelse af private oplysninger. Chlorine is much more electronegative than bromine, as it has a high charge to volume ratio. The chemical reactivity of bromine lies between that of chlorine and iodine. Chlorine is a smaller atom than bromine, and therefore there are less shells of electrons to shield outer electrons from the nucleus, and also as it is smaller the outer electrons will be closer to the positive nucleus and so more strongly attracted.
