A metallic crystal cystallizes into a lattice containing a sequence of layers `ABABAB…`. Any packing of spheres leaves out voids in the lattice. What percentage by volume of this lattice is empty spece?

Text Solution

Verified by Experts

The AB AB AB ….. Type arrangement is known as hcp packing. For hcp, the packing fraction is `0.74`. This means that the empty space is `0.26` or `26%`.
