Actually, we don’t know that the core is solid H2. That’s one of the things Juno is supposed to figure out.

...Considering that gases (noble) can be liquids at low temp and pressure, it's an interesting theory that they can be called solid or metallic. You say the core.(first layer?) I thought the second layer was the one in question...

...Looks like you're on the edge of all that discovery, thanks for sharing it, and hope you stay in touch...
