In the sodium chloride lattice, the co-ordination number of the sodium ions is defined by the number of chloride ions that are nearest to each sodium ion. State the co-ordination numbers for 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
