Sagot :
The smallest number of atoms that could fit inside the unit cell of an element with a body-centered cubic lattice is XM4.
M ion is present in between each edge and one in the center too
so,no.of atoms per unit cell,
((12)*(1/4))+1=4 atoms
{case 1 These are 12 total atoms that are stored between four unit cells and an atom at the center that is not stored with any other unit cell}
X is at the corner of the unit cell so, the no. of atoms per unit cell=
((8)*(1/8))=1
{case 2 These are a total of 8 corners having one atom at each that, is shared between 8 unit cells}
so, the empirical formula of the compound must be
XM₄
As no option is matching with the answer, there is an error in the option also formula X2M is repeated 2 times may be an error
