What is the coordination number of atoms: (a) in a cubic close-packed structure? (b) in a body-centred cubic structure?
(i) Coordination number is the number of nearest neighbors with which a given atom is in contact. In an ionic crystal, the coordination number of an ion refers to the number of oppositely charged ions that surround that ion. (ii) The coordination number of atoms in a (a) cubic close-packed structure is 12. (b) body-centred cubic structure is 8.
