Question

A compound found by elements a and b crystallize in cubic structure of atoms are at corners of cube and b atoms or face centre what is the formula of compound

Answer 1

Answer:if you want to say that a atoms are at the corners and b atoms are at face centres then the answer is ab3

Explanation:a atoms are at corners that means there are 8 a atoms.

one atom at the corner provides its 1/8th part in the unit cell,

therefore,  8*(1/8) atoms of a are there in the unit cell = 1

one atom at the face centre provides its 1/2 part in the unit cell, and there are 6 faces in the cube,

therefore, the number of b atoms in a cube = (1/2)*6 = 3

therefore, formula of compound = ab3
