Which of the following is not
correct?
a.Four spheres are involved in the
formation of tetrahedral void.
b. The centres of spheres in octahedral
voids are at the opices of a regular
tetrahedron.
c. If the number of atoms is N the
number of octahedral voids is 2N.
d. If the number of atoms is N/2, the
number of tetrahedral voids is N.
Answers
Answer:
(C) is not correct (If the number of atoms in N the number of octahedral)
Answer:
The Correct answer is Statement c. if the number of atoms is N the number of octahedral voids is 2N.
Explanation:
a. Four spheres are involved in the formation of the tetrahedral void. This statement is Correct. As there are 4 atoms in each small cube, which form a regular tetrahedron when joined together. In this tetrahedron, there is a tetrahedral void.
b. the centers of the sphere in Octahedra voids are at the apices of a regular tetrahedron. This statement is Correct.
c. if the number of atoms is N the number of the octahedral voids is 2N. This statement is incorrect because the number of Octahedral voids formed will also be N.
d. if the number of atoms is N/2, the number of tetrahedral voids that will be formed is N. this statement is correct because if the number of atoms is N then the tetrahedral voids formed will be 2N.
