Question

A cubic solid is made of two element P and Q. are at the corner of the cube and P at the body- center. what is the formula of the compound ? what are the coordination number of P and Q ?​

Answer 1

Answer:

I hope this answer is helpful...

Explanation:

A cubic solid is made up of two elements P and Q. Atom Q is present at corners of the cube and atom P at the body centre. What is the formula of the compound? ... Hence, the formula of the compound is PQ. As it is a bcc lattice therefore, coordination number is 8 for both P and Q.

${\bf{\green{Given\:that}}}$

Atoms of Q are the corners of the cube and P at the body- centre

Therefore, Number of atoms of Q in one unit cell =8×⅛=1

Number of atoms of P in one unit cell =1

Therefore, Ratio of P and Q atoms = P:Q = 1:1

Therefore, formula of the given compound = PQ

Since it is bcc

Therefore, coordinate number of P and Q = 8
