The central Br atom in Br[Br-]Br is marked as having a valence error. It should not. Both Br and I can expand their octet this way.

Hi Bob,


Yes I can confirm, the issue ticket for your report is still open in our bug tracking system. We are working on a lot of things and this one is still in the queue. If we have fixed it, we will notify you in this topic.


Should we increase the priority for this issue since it is important on your side? If yes, then can you please give us a clue about the importance level?


Best regards,
Istvan

I find bugs in the valence error calculations (such as the one that accepts neutral NO2, the subject of another post) to be among the most pernicious, since they mislead students about some very basic concepts. Users expect the valence error calculations to be accurate, and honestly, the arithmetic is not that difficult. I know I can turn off the valence error checking in the applet, but that leads to other problems.

I understand that these issues are important and we will fix them. Unfortunately it does not mean that we have the capacity to fix them promptly.
