Nearest Neighbour Distance in Magnesium
Lattice Constant of Magnesium HCP Structure
The lattice constant is the distance between the centers of two adjacent unit cells in a crystal lattice. For Magnesium, the lattice constant is given as 0.32 nm.
Nearest Neighbour Distance
In an HCP structure, there are two types of nearest neighbours: the first type of nearest neighbours are those present in the same plane, and the second type of nearest neighbours are those present in the next closest plane. The distance between the nearest neighbours can be calculated as follows:
For the first type of nearest neighbours, the distance is given by:
d1 = a/2
where a is the lattice constant.
For the second type of nearest neighbours, the distance is given by:
d2 = √(3/4)a
Substituting the value of a = 0.32 nm, we get:
d1 = 0.16 nm
d2 = 0.277 nm
Since the question asks for the nearest neighbour distance, we choose the first type of nearest neighbour distance, which is 0.16 nm.
Therefore, the correct answer is option B, which is 0.16 nm.
