Questions: How many atoms are shown in the image? Consider the simple cubic (primitive cube) unit cell shown in this image.

Solution Steps

The image shows a simple cubic (primitive cubic) unit cell.

In a simple cubic unit cell, there is one atom at each of the eight corners of the cube.

Each corner atom is shared among eight adjacent unit cells, so each corner atom contributes 1/8th of an atom to the unit cell.

There are 8 corner atoms, each contributing 1/8th of an atom: \[ 8 \times \frac{1}{8} = 1 \]
