Question

A salt MX has r(M^+)=100 pm and r(X^-)=181 pm. Using the radius-ratio rule (and sqrt2=1.414, sqrt3=1.732), the coordination number of M and the unit cell edge length for the corresponding cubic structure (ions touching along the edge for CN 6; along the body diagonal for CN 8) are

Accepted Answer

Answer

CN 4 and 562 pm

Answer

CN 8 and 325 pm

A salt MX has $r (M^{+}) = 100 pm$ and $r (X^{-}) = 181 pm$ . Using the radius-ratio rule (and $2 = 1.414$ , $3 = 1.732$ ), the coordination number of M and the unit cell edge length for the corresponding cubic structure (ions touching along the edge for CN 6; along the body diagonal for CN 8) are
