Who has higher electron affinity between bromine and Iodine?
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
Why does a aqueous solution of iodine not react with sodium bromide?
Bromine is more reactive than iodine/bromine is higher in the activity series than iodine
Does copper or gold have a higher electron affinity?
Gold; gold has the highest electronic affinity of any atom other than the halogens, due to relativistic effects.
Bromine added to sodium iodide?
Ethanol and NaBr. The delta negative OH dissociates from Sodium creating an +Na ion. The Bromine withdraws the electron density towards itself leaving the Carbon delta +. This means that the -OH will attack the +C removing -Br.
Does chlorine have a higher boiling point than iodine?
iodine is having higher boiling point

Which has higher electron affinity fluorine or chlorine?
Fluorine has higher electron affinity than any other element.
Why does a aqueous solution of iodine not react with sodium bromide?
Bromine is more reactive than iodine/bromine is higher in the activity series than iodine
Do Nonmetals with lower electron affinity have higher reactivity?
No. The most reactive non metal, fluorine, has the highest electron affinity.
Why does bromine have higher ionization energy then lead?
Bromine has less valence shells than lead making the distance between its valence electron and its nucleus less than that of lead. This means that there is greater attraction between the nucleus and electron for bromine and it requires a higher ionisation energy to remove its electron.
Definition of electron affinity?
The energy change that occurs when an electron is added to a neutral atom. This is usually exothermic. Noble Gases are excluded from this. Equation: X(element)+e-(electron)---------> X-1+ energy
Why is the electron affinity for clorine is greater than the electron affinity for iodine?
Generally electron affinity goes up as you go from left to right across the periodic table, and decreases as you go down a column. However, fluorine is an exception -- and the element with the highest electron affinity is chlorine.(Note that the most electronegative element is fluorine however; 'electronegativity' is not exactly the same as 'electron affinity'.)Electronegativity is the ability of an atom in a molecule to draw bonding electrons to itselfElectron affinity is a measure of the energy change when an electron is added to a neutral atom to form a negative ion.The reason that the electron affinity is not as high as might otherwise be predicted for fluorine, is that it is an extremely small atom, and so it's electron density is very high. Adding an additional electron is therefore not quite as favorable as for an element like chlorine where the electron density is slightly lower (due to electron-electron repulsion between the added electron and the other electrons in the electron cloud).
What elements has the largest electron affinity?
AnswerElectron affinity is the energy released when we add an electron to the outermost orbit of the atom. Halogens are the higher in electron affinity, and chlorine has the higher electron affinity than rest of the halogens. The irregularity in the electron affinity trend between Cl and F is due to the small size of the F atom. Although F definitely has a higher attraction for an electron than Cl (as evidenced by its high electro negativity value), the small size of the F atom means that adding an electron creates significant repulsion. Since electron affinity is an energy measurement, the total energy associated with electron affinity winds up being the energy that is released by the electron binding to the nucleus, minus the energy involved in overcoming the electrical repulsion in the outer shell.This makes the fluoride anion so formed unstable due to a very high charge/mass ratio. Also, fluorine has no d electrons which limits its atomic size. As a result, fluorine has an electron affinity less than that of chlorine.
What are the trends and exceptions to the trends in electron affinity?
Down the group electron affinity decreases Across a period electron affinity increases. However, it should be noted that chlorine is having higher electron affinity than flourine due to the small size of fluorine atom)
Does copper or gold have a higher electron affinity?
Gold; gold has the highest electronic affinity of any atom other than the halogens, due to relativistic effects.
Why sulphur have higher negative electron affinity than oxygen?
Due to small size and high electron density of oxygen compared to sulphur, interelectronic repulsion is higher in oxygen, resulting in less energy being released when an electron is added to oxygen, due to lesser stability after electron is added, which is due to the interelectronic repulsion in the small oxygen atom. Hence electron affinity value is lower. It is an abnormality and exception to the general periodic trend of electronic affinity values.
Which element has a higher ability than oxygen to attract electrons?
Fluorine is the only element that has a greater ability than oxygen to attract electrons in that period.Chlorine, Bromine, Iodine, and Astatine all have the same electron affinity as Flourine, with the largest (Astatine) with slightly more.Oxygen is in the Oxygen group/family, in the 6a group of the periodic table, and the other named elements in this answer are all halogens, in the 7a group.
