Question

Which of the following combinations of quantum numbers are allowed for an electron in a one-electron atom? Which are not? Identify the atom or ion corresponding to each of the following descriptions: For each of the following pairs of atoms or ions, state which you expect to have the larger radius. The cesium atom has the lowest ionization energy, 375.7 kJ mol-1, of all the neutral atoms in the periodic table. What is the longest wavelength of light that could ionize a cesium atom? In which region of the electromagnetic spectrum does this light fall? We will see later that H2 has equilibrium bond length of 0.751 A and bond dissociation energy of 433 kJ mol-1, whereas F2 has equilibrium bond length of 1.417 A and bond dissociation energy of 155 kJ mol-1. On the same graph show qualitative sketches of the effective potential energy curve Vcff for H2 and F2.
