potassium metal crystallizes in the form of a body centered cubic structure the number of nearest neighbor atoms for each potassium atom in the Solid is:-
a)2
b)4
c)6
d)8

Dear Student

In BCC lattice the nearest neighbours are the corner atoms.
A BCC structure has 8 corners atoms, so the potassium atom will have 8 nearest neighbours.
Hence, option (D) is correct.
