Heliumide

The possibility of obtaining solid pseudosolutions of inert gases such as titanium argonide, scandium heliumide, etc., has been demonstrated

The remaining pieces are labeled with symbols A₁ to A₇ (main-group molecules including homonuclear ones) , B₁ to B₂ (main-group hydrides and heliumides) , C₁ to C₁₅ (main-group molecules not including the homonuclear ones) , D₁ to D₄ transition-metal hydrides and heliumides), […]
