The correct statement in the following isA. The ionic crystal of `AgBr` has schottky defectB. The unit cell having crystal parameters, `a = b ne c, alpha = beta = 90^(@) , gamma = 120^(@)` is hexagonalC. In ions compound having frenkel defect the ratio `(gamma_(+))/(gamma_(-))` is highD. The coordination number of `Na^(+)` ion in `NaCI` is `4` |
