Sudanshu made a model of the unit cell of diamond. It resembled the unit cell of ZnS. If the unit cell of ZnS has 4 units of ZnS per unit cell. It has the same packing efficiency as ZnS. But diamond is the hardest known substance. (a) What is the number of atoms of carbon per unit cell of diamond? (b) Why diamond is the hardest known substance? (c) What is the value that Sudanshu can derive from these facts?
