The correct answer is `No. 2: 1`

The effective number of atoms in a simple cubic (SC) unit cell is equal to 1.

Detailed Explanation

In a Simple cubic lattice (SC) structure for every corner atom, there are four nearest neighbors in the same plane plus two nearest neighbors one exactly above and the other exactly below that corner atom.

In a Simple cubic unit cell, there are 8 atoms at the corners. Therefore, the total number of atoms in one unit cell is

8 × 1/8 = 1 atom.
