How many anions surround a sodium ion in a crystal lattice of sodium chloride?
Answer
Correct Answer : a ) Six
Explanation :In a crystal lattice of sodium chloride (NaCl), each sodium ion (Na+) is surrounded by six chloride ions (Cl-), and each chloride ion is surrounded by six sodium ions.
This arrangement is often referred to as a face-centered cubic lattice, where the ions are arranged in a cubic pattern with ions at the corners and at the centers of each face of the cube.
Each sodium ion is in contact with six chloride ions, and each chloride ion is in contact with six sodium ions, giving rise to a 6:6 coordination number.
Hence, (a) is the correct answer.
