The number of tetrahedral voids are formed if the number of atoms in a crystal is N/2

Assertion : The octahedral viods have double the size of the tetrabedral voids in a crystal Reason: The number of tetrahedral voids is double the number of octabehedral voids is a crystal

Assertion:A tetrahedral void is surrounded by four spheres and an octahedral void is surrounded by six spheres. Reason:The number of tetrahedral voids is double the number of close packed spheres and number of octahedral voids is equal to number of close packed spheres.

Assertion : The number of tetrahedral voids is double the number of octahedral voids Reason : The size of the tetrhedral voids is half of that of the ochedral void

Number of tetrahedral voids occupied in a unit cell of diamond is
