Question

OI the
1.13
compound? What are the coordination numbers of P and Q?
Niobium crystallises in body-centred cubic structure. If density is 8.55
g cm, calculate atomic radius of niobium using its atomic mass 93 u.​

Answer 1

Answer:

===>> It is given that the atoms of Q are present at the corners of the cube. It is also given that the atoms of P are present at the body-centre. Hence, the formula of the compound is PQ. The coordination number of both P and Q is 8.
