WebJan 24, 2024 · Similarly oxide ion (126pm) is much smaller than chloride ion (167pm). Former is doubly charged where as latter has only single charge. For both these reasons CaO has a much high lattice enthalpy (3414kJ/mol) compared that of NaCl (787kJ/mol) Share. Improve this answer. 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 ...

WebIn chemistry, the lattice energy is the energy change upon formation of one mole of a crystalline ionic compound from its constituent ions, which are assumed to initially be in the gaseous state.It is a measure of the cohesive forces that bind ionic solids.
