Vedclass · Answer

(D) In this unit cell,manganese $(Mn^{n+})$ ions are at the corners and fluoride $(F^-)$ ions are at the centres of each edge.Each corner of a cubic unit cell is shared by $8$ unit cells,but the coordination number is determined by the number of nearest neighbors.Each corner atom is connected to $6$ edge centers in the same unit cell.Therefore,the coordination number of the manganese ion is $6$.

$A$ cubic unit cell contains manganese ions at the corners and fluoride ions at the centres of each edge. The coordination number of the manganese ion is-
