- b)6,6
- c)8,6
- d)6,8
Correct answer is option 'C'. Can you explain this answer?
Verified Answer
Number of neighbours and next - nearest neighbours of K respectively, ...
(c)
Nearest neighbours are along the diagonal at the half distance apart, Diagonal AB = √3a
∴ Distance of the nearest neighbour
Next nearest neighbours are along the cell edge = 520 pm
K-atom at the centre is surrounded by eight K-atoms as nearest neighbours.
In bcc, coordination number is six as next nearest neighbours

Neighbours and Next-Nearest Neighbours of K
Neighbours and next-nearest neighbours are the atoms that are closest to a particular atom in a crystal lattice. The number of neighbours and next-nearest neighbours of K depends on the crystal structure.
Given options are:
a) 8,8
b) 6,6
c) 8,6
d) 6,8
The correct answer is option 'C', i.e., 8 neighbours and 6 next-nearest neighbours.
Explanation:
In a simple cubic lattice, each atom has 6 neighbours and no next-nearest neighbours, but in a body-centred cubic (BCC) lattice, each atom has 8 neighbours and 6 next-nearest neighbours.
K belongs to the BCC lattice, so it has 8 neighbours and 6 next-nearest neighbours.
Therefore, option 'C', i.e., 8 neighbours and 6 next-nearest neighbours is the correct answer.
