Oxidation numbers
« on: February 29, 2008, 10:03:54 AM »
Determine the oxidation number of the specified element in each of the following.
a)N in NF3 b)S in S8 c)Cr in CrO42-
d)P in P2O5 e)C in C12H22O11 f)C in CHCl3

I don't understand the concept. Can someone help explain it and then I'll try posting the possibly right answers. Thanks.

Well, you can start with the textbook definition, or maybe you can draw the electron dot structures of these molecules?

Hey, I'm not judging.  I just like to shoot straight.  I'm a man of science.

I would start here:

It looks like a lot, but it really probably  a lot simpler then you are trying to make it.

Jeez Borek. Even sometimes I refer to your site for information. There is always more there then meets the eye, and it is very well done!

Just thought I would mention that.
