2)A new ionic lattice (AB) adopts a non-ideal NaCl structure, as found with most ionic lattices. The AB compound was found to have a lattice energy of U=-5.35x103 kJ/mol, density of 5.2 g/cm3, ΔHs = + 26 kJ/mol, and the radii values shown below.
| Ionic Radii (pm) | 4 coord. no. | 6 coord. no. | 8 coord. no. |
| A2+ | 138 | 144 | 152 |
| B2- | 180 | 188 | 194 |
For the unit cell of AB what is the length of one of its sides (i.e. the value of "a"; units of pm)?
