Question

Statement: A metallic element crystallises in a lattice containing a sequence of layers as ABABAB and so on. Any packing of spheres leaves out voids in the lattice. $26\%$ per cent by volume of this lattice is empty-spaced.

State whether the given statement is true or false.

• A. True
• B. False

Answer 1

The correct option is A True

Packing fraction of hcp is $74\%$ and so, it has $26\%$ empty space.
