Helium compounds

Helium compounds are chemical compounds that contain helium as a constituent. Helium is a noble gas and is generally considered chemically inert, which means it typically does not form stable compounds under normal conditions. However, there are a few exceptions where helium can be involved in molecular structures or be part of composite materials. 1. **Helium Hydride Ion (HeH⁺)**: This was the first compound predicted to exist, and it was discovered in laboratory conditions in 2020.
