chadn Posted November 16, 2004 Posted November 16, 2004 As far as Im concerned theres not much difference between active and reactive.

albertlee Posted November 16, 2004 Author 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

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 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.... Albert

Gilded Posted November 18, 2004 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

jsatan Posted November 18, 2004 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,

Primarygun Posted November 19, 2004 Posted November 19, 2004 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 although I know little about the scale, It seems to be very familiar to me. Anyone posted this before?
