(i) Simple cubic structure (sc) : Each corner atom is shared by eight surrounding ... WebAn atom at centre of cube belongs only to this unit cell and there is only one body centre in the unit cell. ∴ No. of atoms of P in the unit cell = 1 x 1 = 1 Thus, the formula of compound is PQ or QP. For body centred cubic unit cell, the coordination number is 8:8. ∴ Co-ordination number P = 8 and also coordination number of Q = 8. WebLithium forms body centred cubic structure.
