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» SOLUTION :Atoms Q are located at the CORNER of cube `therefore` Number of Q atoms `= ( 8 XX 1/8) = 1` per UNIT cell P atom are at the body-centre of a cube `therefore`Number of P atoms per unit cell = 1 Ratio of P atom to the Q atoms = 1:1 . `therefore` Formula of a COMPOUND = PQ The co-ordination number of P and Q are 8. |
