Guest qw1222 Posted November 4, 2005 Report Share Posted November 4, 2005 Has anyone done barron tests? from the 1999 edition book? jesus, there are so many mistakes. Can someone please arrange this in increasing size... K+, S2-, Cl-, Ar Link to comment Share on other sites More sharing options...
Guest shesallDAT Posted November 4, 2005 Report Share Posted November 4, 2005 I would have to go with: K+, Ar, Cl-, S-2 (largest) The rationale should be in Barron's somewhere... Link to comment Share on other sites More sharing options...
Guest wishywish82 Posted November 4, 2005 Report Share Posted November 4, 2005 yeah someone should make a test with no mistakes. that's a rotton question, since all the valencies are equivalent to Ar, I'd go with K+ (largest), s, cl, and ar Link to comment Share on other sites More sharing options...
Guest spartacus1212 Posted November 4, 2005 Report Share Posted November 4, 2005 All have same number of electrons, but number of protons from highest to lowest # (smallest to biggest radius) = K+, Ar, CL-, S2- (largest). I've found a few mistakes in the kaplan books too...but not many...bastardos my friend, bastardos. Link to comment Share on other sites More sharing options...
