It would appear.... we may all need to toss out everything we learned about chemistry. Helium that noble gas.... may not be so noble after all.......

A Wild New Helium Compound Could Rewrite Chemistry Textbooks
Here’s a popular high school chemistry fact: Helium atoms don’t interact with other atoms to create compounds. Well, that fact might need some reevaluating.

An international team of scientists think they’ve created a stable helium compound, meaning one composed of both helium and sodium atoms together. The discovery would be wild not only because of the way it goes against some of our basic assumptions of chemistry, but would also help scientists better understand the way atoms act in the high-pressure centers of gas giant planets.
