We attribute the emergence of this dense insulating state not to atom pairing, but to p-d hybridizations of valence electrons and their repulsion by core electrons into the lattice interstices. We expect that such insulating states may also form in other elements and compounds when compression is...

• In other words, the valence shell/ last shell of sodium atom has only one electron. But in sodium ion the last shell has 8 electrons. • Sodium ion has a +1 charge whereas sodium atom is neutral. • Sodium atom is very reactive; therefore, won’t find free in nature. It ex...

Projector augmented wave potentials46 were employed to treat valence-core interactions, whereas Na (2p, 3 s) and Si (2 s, 2p) valence electrons were expanded in plane-waves with a cut-off energy of 600 eV. The Perdew–Burke–Ernzerhof (PBE)47 exchange–correlation functional was ...
