The number of atoms per unit cell of simple cubic is/are
Correct answer: A. One
- A. One
- B. Four
- C. Eight
- D. Six
Explanation
In a simple cubic unit cell, atoms are positioned at each of the eight corners of the cube. Each corner atom is shared among eight adjacent unit cells. Therefore, the contribution of each corner atom to the unit cell is 1/8th of an atom. With eight corners, the total number of atoms per unit cell is calculated as 8 * (1/8) = 1. This is why Option A is correct. Options B, C, and D suggest incorrect numbers of atoms based on different assumptions about the structure and sharing of atoms, which are not applicable to a simple cubic unit cell.

About Physics of Solids
Solids are compared through crystal structure, amorphous arrangement, elasticity, plastic deformation, stress, strain and Young’s modulus. Electrical behavior depends on available charge carriers and band structure, so conductors, insulators and semiconductors must be distinguished from mechanical properties such as strength, stiffness and brittleness.
