The vacant space In close packed structures are called voids?What is the number of tetrahedral voids and octahedral volds in a crystal having n particles ?

The percent void space in close fcc packing of sphere is

Assertion : A tetrahedral void is surrounded by four spheres and an octahedral void is surrounded by six spheres. Reason : In hcp or ccp 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 (A) : In Rock salt type structuires, all the coctahedral voids in the close packing of anions are occupied by cations. Reason(R): In Rock salt structure, the distance of closest apprach between two anions is equal to hal the face diagonal of unit cell.
