Are you looking for an answer to the topic “why is chlorine more reactive than bromine“? We answer all your questions at the website barkmanoil.com in category: Newly updated financial and investment news for you. You will find the answer right below.
Although the bromine nucleus is more positively charged than the chlorine nucleus, the increase in the radius and the extra shielding in the bromine atom outweigh this factor, which means that an electron is more easily attracted into the outer shell of a chlorine atom than that of a bromine atom, so chlorine is more …GCSE. Group 7 elements need to gain electrons to react. Chlorine has less electron shells than bromine and this lack of shielding makes it easier for chlorine to gain electrons. Therefore, chlorine is more reactive.Chlorine is more reactive than iodine since chlorine can gain electrons more easily than iodine.
Why chlorine is more reactive than bromine GCSE?
GCSE. Group 7 elements need to gain electrons to react. Chlorine has less electron shells than bromine and this lack of shielding makes it easier for chlorine to gain electrons. Therefore, chlorine is more reactive.
Why is chlorine more reactive than?
Chlorine is more reactive than iodine since chlorine can gain electrons more easily than iodine.

Is bromine more reactive than chloride?
Because chlorine is more reactive than bromine, it displaces bromine from sodium bromide. The solution turns brown.
Why is chlorine more reactive than bromine mark scheme?
Tick ONE box. Chlorine is more reactive than bromine. This is because chlorine gains more easily.
Which is more reactive chlorine fluorine or bromine?
Chlorine is more reactive than both bromine and iodine. But fluorine is the most reactive of the halogens. So the correct answer to this question is fluorine. If you’re interested as to why the reactivity increases as we go up the group, have a think about the number of core electrons that each element has.
Which one Cl or Br is more electronegative and why?
…
Carbon is More Electronegative Than You Think.
| Element | Electronegativity (Pauling) |
|---|---|
| Cl | 3.2 [3.16] |
| N | 3.0 [3.04] |
| Br | 3.0 [2.96] |
| I | 2.7 [2.66] |
Why is bromine so reactive?
Bromine is a very chemically reactive metal and thus is never pure in nature: due to its 7 valence electrons and high electron affinity, bromine reacts readily, and violently, with the alkali metals.
See some more details on the topic why is chlorine more reactive than bromine here:
Why is chlorine more reactive than bromine? Does it have …
Yes, chlorine is more reactive than bromine because the chlorine atom has fewer shells and the electronic bonding is much stronger.
Why is chlorine more reactive than bromide – The Student Room
GCSE. Group 7 elements need to gain electrons to react. Chlorine has less electron shells than bromine and this lack of shielding makes it easier for chlorine …
Reactivity of the halogens | Physics Forums
But aren’t the bonds between Cl and Cl stronger than Br and Br. So why is chlorine more reactive than bromine since it should be harder to break …
Why is chlorine more reactive than fluorine?
The reactivity is the halogens ability to gain an electron, so number of electrons already in the atom plays a vital role. Chlorine has more electrons so repels a reacting electron with greater force than fluorine, making it less likely to react.
How do you know which halogen is more reactive?
The non-metal elements in Group 7 – known as the halogens – get less reactive as you go down the group. This is the opposite trend to that seen in the alkali metals in Group 1 of the periodic table . Fluorine is the most reactive element of all in Group 7.
Does chlorine or bromine have a more negative electron affinity?
Chlorine does have a higher electron affinity than bromine. So, why does that happen? As you know, both chlorine and bromine are located in group 17 of the periodic table, which implies that they have seven electrons on their outermost shell.
Is Cl A better nucleophile than Br?
In polar aprotic solvents (e.g. DMSO, acetone) the order is reversed, and the most basic nucleophiles are also the most nucleophilic. (F- > Cl – > Br – > I – ).

Why chlorine can displace bromine from sea water?
Chlorine is able to displace bromine from sea water because chlorine is more reactive than bromine.
Why is fluorine more reactive than bromine?
Reactivity is an elements ability to gain an electron. So the better it is at “stealing” electrons, the more reactive it will be. The thing that makes fluorine so reactive is its electronegativity. … Therefore, since fluorine has a higher electronegatvity than chlorine, fluorine is more reactive.
Is chlorine reactive or nonreactive?
Chlorine is a halogen in group 17 and period 3. It is very reactive and is widely used for many purposes, such as as a disinfectant. Due to its high reactivity, it is commonly found in nature bonded to many different elements.
Is chlorine more reactive than bromine and/or iodine?
The order of reactivity is chlorine > bromine > iodine. This is because chlorine could displace bromine and iodine, bromine could only displace iodine, but iodine could not displace chlorine or bromine.
Which of chlorine fluorine or bromine is the least reactive halogen?
Its oxidation states vary from -1, +1, 3, 4 and 5. Bromine is more reactive than iodine, but not as reactive as chlorine.
Which is the most reactive among the halogen fluorine chlorine bromine iodine?
The correct answer is option 1, i.e., Fluorine. Fluorine is the most reactive Halogen. Not just in the halogen family, but in the whole periodic table it is the most reactive non-metal. It belongs to second period and group 17 of the periodic table.
Why is chlorine more electronegative than carbon?
…
The carbon-chlorine bond.
| carbon | 2.5 |
|---|---|
| chlorine | 3.0 |
Why does chlorine have a higher electronegativity than iodine?
There is more strong nuclear force between the electron and nucleus of chlorine, and hence the electro negativity of chlorine is higher than idea.
How do you know which element is more electronegative?
Electronegativity varies in a predictable way across the periodic table. Electronegativity increases from bottom to top in groups, and increases from left to right across periods. Thus, fluorine is the most electronegative element, while francium is one of the least electronegative.

How do you know which elements are more reactive?
The elements toward the bottom left corner of the periodic table are the metals that are the most active in the sense of being the most reactive. Lithium, sodium, and potassium all react with water, for example.
Is chlorine more reactive than sodium?
So, it takes more energy to get chlorine to react than sodium. A related measure is the electron affinity – the change in energy due to adding an electron. Again, the lower magnitude of -52.8 kJ/mol for sodium compared to -349 kJ/mol for chlorine indicates that sodium will be more reactive.
