Number of atoms per unit cell in B.C.C. is
(3) 2
In a body-centred cubic (bcc) unit cell:
Corner atoms: 8 18 = 1
Body-centre atom: 1 1 = 1
∴ Number of atoms per unit cell = 1 + 1 = 2
Answer: (3)
When Zn converts from melted state to its solid state, it has hcp structure, then find the number of nearest atoms.
The cations and anions are arranged in alternate form in
Cations and anions combine in a crystal to form the following type of compound
In a cubic crystal, A-atoms are placed at every corner and B-atoms at the centre of every face. The formula of the compound is
