While it's been theorized that high pressure essentially squeezes sodium's electrons out into the spaces between atoms, researchers' quantum chemical calculations show that these electrons still very much belong to the surrounding atoms and are chemically bonded to each other.
Pincho says... Pure imagination, no such thing as chemical bonding at that scale. Chemicals are a story that allows scientists to ignore physics, the same as relativity, and particle physics. Bonding is a force towards an area of least resistance with spin... you know.. physical, as in physics.
