BLAZE DOWNLOAD NOW REVOLUTIONS Question 12 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 It is given that the atoms of Q are present at the corners of the cube. Therefore, number of atoms of Q in one unit cell = 8 x 1/8 = 1 It is also given that the atoms of P are present at the body-centre. Therefore, number of atoms of P in one unit cell = 1 %3D This means that the ratio of the number of P atoms to the number of Q atoms, P:Q = 1:1 Hence, the formula of the compound is PQ. The coordination number of both P and Q is 8. Previous Question Next Question...(My doubt is why the coordination no. Of P is 8)
