100-year-old chemistry rule proven false, textbook updates needed

I love the fact that scientists understand that what we know and observe is sometimes subject to change based on new information. 

It's what mouth breathers use to try and undermine scientific endeavor, because they really do not understand what makes it great. 

Here's a case where a chemist wrote rules around chemical bonds. And that rule held up to scrutiny for about 100 years and thus chemistry always taught it to us. 

But now, we've discovered that this rule is *not always* true and it upends some of what we know. 

I appreciate that the article notes this:

Next time someone says something is impossible, ask whether anyone has actually tried it recently. You might be surprised by what is possible when you stop assuming and start experimenting.

Yes! Experiment and learn!
