Assertion (A): The total number of atoms present in a simple cubic unit cell is one.
Reason (R): Simple cubic unit cell has atoms at its comers, each of which is shared between eight adjacent unit cells.
(a) Assertion and Reason both are correct statements and Reason is the correct explanation for Assertion.
(b) Assertion and Reason both are correct statements but Reason is not the correct explanation for Assertion.
(c) Assertion is correct but Reason is wrong.
(d) Assertion is wrong but Reason is correct.
(a) Assertion and Reason both are correct statements and Reason is the correct explanation for Assertion.
Explanation:
In simple cubic unit cell, only comers are occupied by atoms. Thus, total number of atoms present in the unit cell will be one.
(Z = 1/8 x 8 = 1).
