According to Zumdahl, Group 7A elements (halogens) follow the expected behavior or periodicity as you follow top to bottom. The numbers (top to bottom) are getting closer to 0, so they are decreasing in electron affinity. Bromine has a higher negative # therefore it is a higher electron affinity.---papajohn
Bromine has a higher electron affinity.
Iodine's electron configuration is 2, 8, 18, 18, 7; bromine's is 2, 8, 18, 7. At the simplest level of modelling there is one more electron shell occupying space in an iodine atom than in one of bromine.
Fluorine, chlorine bromine and iodine have seven electrons in their valence shells, and they all need one electron to have stabilized electron configuration. Therefore they are grouped in Group 17 (halogen group) of periodic table.
Bromine has a SMALLER atomic radius because it has one more electron shell than Iodine. On the periodic table, atomic radius of an atom decreases across a period and increases down a group. Since Bromine and Iodine are in the same group, you know Bromine has a smaller atomic radius because it is in a lower period.
No. Bromine is more reactive than iodine. Therefore, bromine will displace iodine.
Bromine has a higher electron affinity.
Yes. It's true. Chlorine has the highest electron affinity, then Fluorine, Bromine and Iodine
Bromine has more nuclear charge as compared to iodine. So, bromine easily attracts an electron and hence more reactive.
Iodine's electron configuration is 2, 8, 18, 18, 7; bromine's is 2, 8, 18, 7. At the simplest level of modelling there is one more electron shell occupying space in an iodine atom than in one of bromine.
The Halogens, Fluorine, Chlorine, Bromine, Iodine and Astatine.
Fluorine, chlorine bromine and iodine have seven electrons in their valence shells, and they all need one electron to have stabilized electron configuration. Therefore they are grouped in Group 17 (halogen group) of periodic table.

No. Bromine is more reactive than iodine. Therefore, bromine will displace iodine.
Bromine is in 4th period of periodic table.
No,. The halogens will gain 1 electron when they react if electrons are exchanged.
is it so? Bromine is more electronegetive than Iodine
