wat is the role of electron transfer in redox reactions?

 

[~[TaLeC]~]

Down below somewhere is a thread on electron transfer reactions...that explains the majority of it...but basically the electron transfer allows for the displacement of metal from a solution of it's ions by another more reactive metal....

yeah, and electron transfer is what allows atoms to oxidise (lose electrons) and reduce (gain electrons)

redox.... one atom gains, one loses. role? its what happens.and then stuff happens as a result

i guess its just the stupid wording of the syllabus.

spose. redox is just the transfer of an electron to the more electronegative atom. ie: zinc is oxidised, Cu is reduced ina simple lelanche(watever it is) cell. the differences in elctronegativity cause the voltage. the change fromatom to ion of the more active elemnt releases nrg.

electionegative... thats the one that wants to gain ions???

ie, if something is more electronegative, they're more likely to gain an ion???

yep, i think if somethin' is more electronegative, its more likely to gain an electron (not an ion.. )

lol yea your right aww would have lost a mark there, nooo hehe

yeah electronegative is tendency to form an anion. ie: group 7's are way elctronegative, group 1s are far from it.

yeah, electoaffinity, is the tendency to give out electrons like the group one metals.

lol, yea and hence their more electropositive

but remember if this was like a 3/4 mark question, then put in examples and half equations. Think I saw a question similar to this in one of the papers I did.
