Studies of the Earth's atmosphere have shown that more than 90% of xenon is depleted — the so-called missing Xe paradox. Now a theoretical study shows that Xe and Fe/Ni can form inter-metallic compounds of XeFe3 and XeNi3 under conditions found in the Earth's inner core, and could provide a solution to the puzzle.
