chadn Posted November 16, 2004 Share Posted November 16, 2004 As far as Im concerned theres not much difference between active and reactive. Link to comment Share on other sites More sharing options...

albertlee Posted November 16, 2004 Author Share Posted November 16, 2004 Thx Chadn... By the way, as a cation, does the element with lower electronegativity tend to loose the electrons??? Meanwhile, as an anion, does the element with higher electronegativity tend to accept the electrons?? Albert Link to comment Share on other sites More sharing options...

Yes. That's a basic concept. In electrolysis, composition of chemical is also a factor which affects the outcome of both electrode, cathode and anode. I haven't learnt that yet, maybe next year. Can't give you any examples. By the way, what kind of electrode and substance are used to displace potassium from its stable compound into a potassium metal ?

albertlee Posted November 17, 2004 Author Share Posted November 17, 2004 By the way, why the amount of protons is not in direct proportion to the strength of the electronegativity??? since it is the proton which attracts/holds the electrons....

Gilded Posted November 18, 2004 Share Posted November 18, 2004 http://www.wellesley.edu/Chemistry/chem241/en.html Some info about calculating electronegativity in common use. Seems quite complicated though. Edit: Also, found this one from the "strongest acid" thread (stated by budullewraagh): according to linus pauling: X=((0.31(n+1+or-c))/r)+0.50 n=valance electrons c=formal valance charge on atom. is positive or negative depending on polarity of charge. r=covalent radius Link to comment Share on other sites More sharing options...

jsatan Posted November 18, 2004 Share Posted November 18, 2004 lol. I'v just finally got what this is about as regards the solutions in the same pot, lol. i forgot that you was passing a current through it, silly me, Link to comment Share on other sites More sharing options...
