1.	A cubic solid is made of two elements P and Q. Atoms of Q are at the corners of the cube and P at the body-centre. What is the formula of the compound ? What are the coordination numbers of P and Q ?
Answer» <P> Solution :Number of atoms of Q in the unit CELL `=(1)/(8)xx8=1` Number of atoms of P in the unit cell = 1 Hence the formula is PQ. Coordination number of each = 8.
