Question

If the ratio of coordination no. of a to that of b is x:y then ratio of no. of atoms of a:b in unit cell

Answer 1

As atoms of Q are present at the 8 corners of the cube

Number of atoms of Q in the unit cell = 18×8 = 1

Atoms P are present at the body center, therefore number of atoms of P in the unit cell = 1

Ratio of atoms = P : Q = 1 : 1

Answer 2

Answer:

Explanation:

Content:

Coordination number of a=Number of atoms of b and vice versa

Hence, ratio is reciprocal of the given one,y:x, hope you understood,if not ask me.
