I need help answering this question, Why is chlorine more reactive than bromide
it is with 3 marks. I know the answer but I'm not sure how to write in words. Please could someone help me


Has a greater electronegative value.
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.

Do you know the definition of electronegativity?

If you apply it, can you see why you are wrong?

Either take my advice, or don't, I care not.

If you don't though, I'd cross your fingers that something like this doesn't come up on any of your exams as you will not score the marks.

Do you know why your suggestion was wrong?
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. Chlorine is more reactive than bromine because the chlorine molecule is has fewer shells in total therefore the electronic bonding is stronger. Hope this helped xx goodluck
