In the ionic lattice of sodium chloride, each ion is bonded to how many neighbours?
ASix neighbours
BTwo neighbours
CFour neighbours
DEight neighbours
Answer & Solution
Correct answer: A. Six neighbours
1. An ionic solid is a repeating three-dimensional arrangement rather than a set of pairs.
2. Each ion is bonded to all of the surrounding ions.
3. In the sodium chloride structure that number is six.
4. That is why no single pair can be picked out as a molecule.
