Define (a) simple or primitive unit cell (b) body-centred unit cell ( c) face-centred unit cell (d) end-centred unit cell.

In face-centred cubic unit cell :

Match the type of unit cell given in Column I with the features given in Column II. coloumn I (i) primitive cubic unit cell (ii) Body centred cubic unit cell (iii) Face centred cubic unit cell (iV) End centred orthohomic unit cell Column -II (a) Each of the three perpendicular edges compulsorily have the different edge length i.e., anebbec (b) Number of atoms per unit cell is one (c) Each of the three perpendicular edges compulsorily have the same edge length i.e., a=b=c (d) In additions to the contribution from the corner atoms the number of atoms present in a unit cell is three.
