Question

The ratio of close packed atomes to octahedral holes in hexagonal close packing is
a) 1:1
b) 1:2
c) 2:1
d) 1:3

Answer 1

The answer will be 1: 1 here if the close-packed atom is taken up as the 1 then the octahedral holes will fall up to 1.

These types of holes are usually formed when the single atom will get in touch with 3 atoms that are in the below layer.

The rule is that n closed sphere have n octahedral
