What is the coordination number of a simple cubic (SC) unit cell?

Right Answer is:

6

SOLUTION

The coordination number of the simple cubic (SC) unit cells is 8.

Detailed Explanation

The coordination number 1s the number of nearest atoms surrounding the given atom. The greater the coordination number, the more closely packed will be the structure.

There are six nearest neighbouring atoms for every atom in a simple cubic (SC) unit cell, in other words, every atom in a SC unit cell is surrounded by 6 other atoms, thus coordination number of SC unit cell is is 6.
