Problem

Four ionic compounds are listed below along with the sum of their ionic radii (in picometres). • LiF,

r=204\,\text{pm}

• NaF,

r=231\,\text{pm}

• MgO,

r=222\,\text{pm}

• SrO,

r=304\,\text{pm}

Based only on this information, which compound is predicted to have the greatest magnitude of lattice energy? a) SrO b) MgO c) LiF d) NaF
