Explanation:
Unit Cell Structure of NaCl:
- NaCl (sodium chloride) crystallizes in a cubic unit cell structure.
- Each unit cell of NaCl consists of chloride ions arranged in a face-centered cubic lattice.
Composition of NaCl Unit Cell:
- In a NaCl unit cell, there are equal numbers of sodium (Na+) and chloride (Cl-) ions.
- Each sodium ion is surrounded by 6 chloride ions in an octahedral arrangement, and each chloride ion is surrounded by 6 sodium ions.
Calculation of NaCl Unit Cell Composition:
- To determine the number of sodium ions in a unit cell of NaCl, we need to consider the coordination number.
- Since each sodium ion is surrounded by 6 chloride ions, there are 6 sodium ions around each chloride ion.
- Therefore, in a NaCl unit cell, there are 6 chloride ions surrounding each sodium ion.
- Since there is 1 sodium ion at the center of the unit cell, it is surrounded by 6 chloride ions, making the total number of chloride ions in the unit cell 6.
Conclusion:
- The correct answer is: 6Na ions in a unit cell of NaCl.
