Because if you compare the melting points (AlCl3 even sublimates @ 180 C) you’ll see that MgO melts way higher. This is due to the molecular nature of AlCl3. So this is either a question that expects you to know this or idk 1 poppingfresh • 3 yr. ago

WebFeb 28, 2024 · Consequently, we expect RbCl, with a (−1)(+1) term in the numerator, to have the lowest lattice energy, and GaP, with a (+3)(−3) term, the highest. To decide whether BaS or CaO has the greater lattice energy, we need to consider the relative sizes of the ions because both compounds contain a +2 metal ion and a −2 chalcogenide ion. WebSep 6, 2024 · The high melting point of ionic compound reflects its high lattice energy. When ions are tightly packed together of an ionic substance, it has a higher melting point than another ionic substance with ions that do not pack well (recall that this packing depends on the ratio of ionic radii of positively and negatively charged ions, which changes ...
