Question

The size of an octahedral site formed in a closest packed lattice as compared to tetrahedral site is​

Answer 1

Answer:

In the closed packed lattice the number of octahedral voids present in a lattice is equal to the number of close packed particles, the number of tetrahedral voids generated is twice this number.

Explanation:

The size of an octahedral void formed in a closed packed lattice as compared to tetrahedral void is larger.

This is apparent from the radius ratio. It is the ratio of the radius (r) of the atom or ion which can exactly fit in the octahedral void formed by spheres of radius R.

For tetrahedral voids, the radius ratio is 0.225

For octahedral voids, the radius ratio is 0.414
