How many electrons does a neutral atom of indium have? 49 How does this element complete its octet? Indium forms compounds with chlorine; one example is the formation of InCl (indium (I) chloride). What electron do you think indium gave up? Why?arrow_forward1. Below is a list of enthalpy changes for the Born-Haber cycle for the formation of solid LiF from Li(s) and F(g). Use these data to determine the lattice energy for the formation LiF(s). Li(s) → Li(g) ΔH1 = +162 kJ/mol Li(g) → Li+(g) + e- ΔH2 = +520.2 kJ/molF2(g) → 2F(g) ΔH3 = 154 kJ/mol F(g) + e- → F-(g) ΔH4 = -328 kJ/molLi(s) + 1/2F2(g) → LiF(s) ΔHf = -612 kJ/mol Select an answer and submit.

- Given the following enthalpy values for Na and Cl, calculate the lattice energy of NaCl using the Born- Haber cycle. for Na = 107.5 kJ/mole for Na = 495.8 kJ/mole for Cl, = 242.6 kJ/mole AHO sublimation AH ionization energy AHO dissociation energy ΔΗΡ electron affinity TOr Cl, = -348.6 kJ/mole AH formation for NaCl(s) = -4l1.2 kJ/molearrow_forwardLattice energies and electron affinities are very difficult to measure experimentally. Fairly reliable theoretical values for lattice energies can be calculated from simple models. The Born-Haber cycle can then be used to estimate electron affinities. Use the data below to calculate the electron affinity of iodine (in kJ mol-1), where a negative EA value indicates a favourable anion formation.
