Csi charge chemistry
Caesium iodide or cesium iodide (chemical formula CsI) is the ionic compound of caesium and iodine. It is often used as the input phosphor of an X-ray image intensifier tube found in fluoroscopy equipment. Caesium iodide photocathodes are highly efficient at extreme ultraviolet wavelengths.

WebJul 10, 2024 · Comparable replacement: ΔH lattice(CaO) = −3464 kJ/mol. Compare that to these: ΔH lattice(KBr) = −688 kJ/mol. ΔH lattice(CsI) = − 604 kJ/mol. So, we were correct. The larger negative value we have for the lattice energy, the more energy released when the lattice was formed, and thus the stronger the lattice structure and the higher the ...
Webcharges increase. Thus, we expect the lattice energy of CaO, which has 2+ and 2–ions, to be the greatest of the three. The ionic charges are the same in NaF and CsI. As a result, the difference in their lattice energies depends on the difference in the distance between ions in the lattice.
