Compound with the bigger lattice energy
WebWhich has the larger lattice energy, Al 2 O 3 or Al 2 Se 3? Solution In these two ionic compounds, the charges Z + and Z – are the same, so the difference in lattice energy will depend upon R o. The O 2– ion is smaller than the Se 2– ion. Thus, Al 2 O 3 would have a shorter interionic distance than Al 2 Se 3, and Al 2 O 3 would have the ... WebThe lattice energies of ionic compounds are relatively large. The lattice energy of NaCl, for example, is 787.3 kJ/mol, which is only slightly less than the energy given off when natural gas burns. The bond between ions of …
