.9% Resources O Hint Consider an ionic compound, MX,, composed of generic metal M and generic gaseous halogen X. • The enthalpy of formation of MX, is AH; = -605 kJ/mol. • The enthalpy of sublimation of M is AHsub = 129 kJ/mol. • The first, second, and third ionization energies of M are IE, = 691 kJ/mol, IE2 = 1581 kJ/mol, and IE3 = 2627 kJ/mol. • The electron affinity of X is AHEA = -361 kJ/mol. (Refer to the hint). • The bond energy of X, is BE = 163 kJ/mol. Determine the lattice energy of MX3. AHjattice kJ/mol about us privacy policy terms of use contact us help careers

or diamagnetic? Explain your answer. 1 4. What relationship does Zeff have with periodic trends of atomic size, ionization energy, and electron affinity? The conceptual rationale/explanation is extremely important. A complete answer will include the trend from left to right as well as top to bottom of the periodic table with an explanation on how Zeff does or does not impact these trends.

Energy of Interaction of Point Charges Coulomb's Law yields an expression for the energy of interaction for a pair of point charges. V = V is the energy (in J) required to bring the two charges from infinite distance separation to distance r (in nm). Q1 and Q₂ are the charges in terms of electrons. (i.e. the constant in the above expression is 2.31x10-19 J nm electrons-2) d For a group of "point" charges (e.g. ions) the total energy of interaction is the sum of the interaction energies for the individual pairs. Calculate the energy of interaction for the square arrangement of ions shown in the diagram below. (+2) 2.31 x 10-1⁹Q1 Q2 d T d = 0.900 nm. (+2) d
