Which one of the following has the largest lattice energy nabr?

NaF

Which of the following compounds will have the largest lattice energy?

AlBr3 have the largest lattice energy. Because of the greater charge on Al3+ ions and Br’ as lattice energy is directly proportional to the charges of the combing atoms.

Why does mgcl2 have high lattice energy?

Magnesium ions are smaller than sodium ions, and oxide ions are smaller thanchloride ions. That means that the distance between the positive and negative ions is quite a lot less in MgO than in NaCl, and so the forces of attraction will be greater in MgO.

What is the lattice energy of K2S?

K2S: sulfide: 1979 Draw the Lewis structure for Li2S, Rb2S, and K2S. Doc Brown’s Chemistry Chemical Bonding GCSE/IGCSE/O/A Level Revision Notes. Therefore, the lattice energy (the amount of energy required to completely separate one mole of a solid ionic compound into its gaseous ions) = + 787 kJ.
