- At large interatomic separations, an alkali halide molecule MX has a lower energy as two neutral atoms, M+X ; at short separations, the ionic form (M+)(X) has a lower energy. At a certain distance, Rc , the energies of the two forms become equal, and it is near this distance that the electron will jump from the metal to the halogen atom during a collision. Because the forces between neutral atoms are weak at large distances, a reasonably good approximation can be made by ignoring any variation in potential V(R) for the neutral atoms between Rc and R= . For the ions in this distance range, Rc is dominated by their Coulomb attraction. (a) Express Rc for the first ionization energy of the metal M and the electron affinity of the halogen X. (b) Calculate Rc for LiF, KBr, and NaCl using data fromAppendix F.A gold nucleus is located at the origin of coordinates, andan electron is brought to a position 2 Å from the origin inthe 1y direction.(a) Calculate the force on the gold nucleus exerted by theelectron giving its components Fx and Fy.(b) Calculate the potential energy of the gold nucleus andthe electron.Nitrogen has a greater first ionization energy than phosphorus. What is the best evidence to supportthis observation?
- Let’s try building a one-dimensional crystal lattice from the scratch. Consider an atomic nucleus carrying Z numberof protons. Assume that the Coulomb’s law holds in this situation. We take many of such nuclei and start placing themat a distance a from each other along a straight line. So, we end up constructing a very long (perhaps, infinite if we couldactually have an infinite number of nuclei) straight chain of equi-spaced nuclei. Can you approximately draw the potentialenergy seen by a free electron in this lattice? A free electron is the one that is free to roam around the lattice, just likethe ones in a metal. A good way to attack this problem would be to start by drawing the potential energy of the electronwhen there was just one nucleus present. After this, you can think that when you bring the nuclei close, they start sensingeach others’ presence through the electric field.The contour representation zof one of the orbitals for then = 3 shell of a hydrogen atomis shown here. (a) What is thequantum number l for thisorbital? (b) How do we label thisorbital? (c) In which of the followingways would you modifythis sketch if the value of themagnetic quantum number, ml,were to change? (i) It would bedrawn larger, (ii) the number of lobes would change, (iii) thelobes of the orbital would point in a different direction, (iv)there would be no change in the sketch. [Section 6.6](ii) How would you expect the second ionization energies for Na and Mg to compare? Explain using both a qualitative and quantitative (Slater’s rules) argument. (iii) Does your answer for (ii) correspond to what you know about the common ions formed by Na and Mg? Explain.
- Determine the electronic configration of transition metal ion: NiOFor the H atom, the transition from the 2p state to the 1sstate is accompanied by the emission of a photon with anenergy of 16.2 × 10-19 J. For an Fe atom, the same transition (2p to 1s) is accompanied by the emission of X-raysof 0.193-nm wavelengths. What is the energy differencebetween these states in iron? Comment on the reason forthe variation (if any) in the 2p-1s energy-level spacing forthese two atoms.(a) Account for formation of the following series of oxidesin terms of the electron configurations of the elementsand the discussion of ionic K2O, CaO, Sc2O3, TiO2, V2O5, CrO3.

Calculate the enthalpy changes in the following general reactionfor each case:MnOm(s) + H2(g)----->nM(s) + mH2O(g)(You will need to write the balanced equation for each caseand then compute ΔH°.) (d) Based on the data given, estimatea value of ΔHf° for Sc2O3(s).
