Question

how do we get to know about atoms in tetrahedral void and octahedral void , ?????​

Answer 1

Answer:

As you see that tetrahedral voids are triangular in shape. When two such voids combine, from two different layers they form an octahedral void. So when the tetrahedral void of the first layer and the tetrahedral void of the second layer align together, they form an octahedral void.

Answer 2

Answer:

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. ... If the smaller ion is small enough then tetrahedral voids are occupied, if bigger, then octahedral voids are occupied
