Question

Find out the ratio of maximum no. Of triangular voids and maximum no. Of rectangular voids formed by the 9 atoms according to hcp and square close packing in 2D

Answer 1

Answer:Ratio is 2:1

Here,No.of triangular voids(tetrahedral voids)=18

No. of octahedral voids(rectangular voids)=9

Ratio=18:9

=2:1

Explanation:

we know,Tetrahedral voids=2×No.of atoms.

Octahedral voids=No.of atoms
