I have done some experimenting with the element selenium and have written a webpage about this. The reactions are quite interesting, but I could not
find any literature, explaining what I observe. I have given my own explanation.
Comments on the explanation are welcome. If it can be backed up with literature that would be nice, if there are errors in it, then I also would like
to know so that it can be corrected.
Here follows the webpage:

I think that even without explanation this is quite interesting on its own.

Good to see a new webpage again.
This is a very interesting one, this is the chemistry I like!
I wonder what tellurium would do, when used instead of selenium. I might try it myself, as I have all the needed materials.
I would be very wary when performing experiments where H2Se might evolve. That stuff is mch more toxic than phosgene, HCN or even arsine!!!

Have you looked at the symmetry aspects of these results? My inorganic, such as it was, was based on group theory.

@Jor: I also tried with Te, but that does not work. Te does not dissolve in solutions of Na2S, not even on strong boiling. I'll modify the website,
making a remark that this does not work for Te.
@chemrox: I do see the similarities of some of my results, but how should I relate this to group theory? Deeper insights are always welcome.
EDIT: Webpage is modified, a remark about the non-reactivity of tellurium is added at the end of the page.

I think it would come handy to look at
Greenwood, N. N.; Earnshaw, A. Chemical Elements; 2nd edition
I remember it had a nice section about sulfur and selenium chemistry
