In the sodium chloride lattice, the number of chloride ions surrounding each sodium ion is known as the co-ordination number of the sodium ions. What are the co-ordination numbers of the sodium ions and the chloride ions in the sodium chloride lattice?
- Asodium ions: 4, chloride ions: 6
- Bsodium ions: 6, chloride ions: 4
- Csodium ions: 6, chloride ions: 6
- Dsodium ions: 8, chloride ions: 6
