Some of these questions do have answers, but these answers have negative votes. Only questions with upvotes will be removed from the list. In addition, this list has new questions sprinkled throughout! That means other questions have become popular and need attention, please take a look at the list and answer what you see fit.

How you can help:

  1. Answer some of these questions!
  2. Edit questions to make them more polished.
  3. Start a bounty on some of the more interesting questions.
  4. Support askers and answerers with upvotes where deserved. If you take a look at the edits made to this question, you can find questions that have been answered by the lovely members of the community.

I modified a query to fit Chem.SE to give us unanswered questions (that are open) and have a high number of views. You can also run the query for one or two answers if you want.

I did find that some questions were quite popular and disappointingly did not contain any answers.

If anyone would like to handle some of these questions, that would be amazing!

Please edit these questions as you see fit (and fix any weird tags.) There is a lot of re-titling to be done and much-needed language cleanup or clarity in the body of the questions. Please upvote the good ones and downvote the bad ones into oblivion.

Here is the query.

Below are the Top 20 questions that need answers. Why twenty? I feel that more variety in the questions shown here increases their chance of getting answers.

    $\begingroup$ #12 (unpaired electrons and magnetic moment) seems pretty much a homework question, but that could just be me... $\endgroup$
