Webbody-centred cubic A term used in crystallography for a cubic (isometric) molecular structure in which a cube-shaped lattice is formed with one atom in the middle and four … As a rule, since atoms in a solid attract each other, the more tightly packed arrangements of atoms tend to be more common. (Loosely packed arrangements do occur, though, for example if the orbital hybridization demands certain bond angles.) Accordingly, the primitive cubic structure, with especially low atomic packing factor, is rare in nature, but is found in polonium. The bcc … larissa neto lueska
