What do you get when you mix iron lithium and neon?

Iron, lithium, and neon do not actually mix, nor do they chemically react with each other (although iron and lithium react with other elements such as oxygen). Iron is much denser than lithium, so if you poured these two metals into a container in their molten state, the lithium would just float on top of the iron. And Neon is an inert gas.
