Why O.S. of -1 more stable?
Doesn't mean the more -ve o.s. is, more stable the atom is
correct?
Edited to add : Ok fair enough, you were asking a question. But
nonetheless, when answering questions in the A level exams, my
point remains, don't lose marks by being ambiguous in your
phrasing. Always be as specific as possible.
Ya know, it's annoying when you (ie. Singapore JC students) say
things like that, and you'll lose marks in the A level exams for
such ambiguous phrasing. They way you phrase it, makes you appear
simple minded (ie. oversimplifying matters due to lack of depth of
understanding) or dogmatic (ie. blindly memorizing school notes
without deeper understanding), because it makes you seem to think
"the more -ve o.s. is, more stable the atom is" holds true for all
elements.
Obviously (at least it's obvious to me and should be obvious to
anyone who truly understands Chemistry, but apparently this doesn't
necessarily include the majority of Singapore JC students or even
some teachers and tutors, does it?), metals being electropositive
will find positive OSes more stable, and non-metals being
electronegative will find negative OSes more stable.
As for the exact unique OSes preferred by each individual
element, you can go figure out for yourself, and/or research
online, and/or ask your school teacher and/or private tutor. At A
levels, if you really understand your A level Chemistry, then
you'll begin to get a glimpse of understanding as to the myriad of
chemistry factors (some opposing each other) contributing to why
different elements (eg. different transition metals) have different
unique preferred OSes.
PS. Don't ask any further questions here on the forum about
this subtopic, go research yourself or ask your school teacher or
private tutor.
