Each unit cell of NaCl consists of 14 Cl ions and 1) 13 Na + 2)14 Na+ ...
Explanation:
1. 14 Na+ ions
- In a unit cell of NaCl, there is one Na+ ion for every Cl- ion, as the compound has a 1:1 ratio of Na+ to Cl- ions.
- Since there are 14 Cl- ions in the unit cell, there must be an equal number of Na+ ions to maintain electrical neutrality.
- Therefore, there are 14 Na+ ions in each unit cell of NaCl.
2. 13 Na+ ions
- This option is incorrect because the number of Na+ ions should be equal to the number of Cl- ions in the unit cell to maintain charge balance.
- Having only 13 Na+ ions would result in a charge imbalance, which is not possible in a stable compound like NaCl.
3. 6 Na+ ions
- This option is incorrect as well because having only 6 Na+ ions in the unit cell would not be sufficient to balance the charge of the 14 Cl- ions present.
- Again, maintaining electrical neutrality is crucial in ionic compounds like NaCl.
4. All are wrong
- This option is incorrect because as explained above, there are indeed 14 Na+ ions in each unit cell of NaCl to balance the charge of the 14 Cl- ions.
Therefore, the correct answer is 14 Na+ ions in each unit cell of NaCl.
