Second nearest neighbours of na ion in nacl unit cell is A) 4 B) 6 C)...
Explanation:
In NaCl unit cell, Na+ ion is surrounded by 6 Cl- ions which are its nearest neighbours. The second nearest neighbours are the 12 Cl- ions which are in contact with the 6 nearest neighbour Cl- ions. But since each of these 12 Cl- ions is also the nearest neighbour of some other Na+ ion, only half of them (i.e. 6) can be considered as the second nearest neighbours of the Na+ ion in question.
Answer:
Hence, the correct option is C) 8.
