This "nucleus" behave just like a single proton that we started with,
Each bond between two atoms share two electrons. In three dimensions, all the bond angles are equal. This lattice has no free electrons, this would makes the element non-conductive and very much less reactive compared to the previous element, Li. It would be more crystalline than metallic. Since there is only two linkage between atoms in the lattice, this element is expected to be brittle.
