What is the electron configuration of a ground-state Fe2+ ion?

Experimentally, the electron affinity for fluorine can be determined by using a laser light to ionize the anion of the element in the gas phase: F (g) + hv → F (g) + e- If the electron affinity is 328 kJ/mol, calculate the wavelength (in nanometers) of the photon corresponding to the electron affinity for fluorine.

Photoelectron spectroscopy applies the principle of the photoelectric effect to study orbital energies of atoms and molecules. High-energy radiation (usually UV or X-ray) is absorbed by a sample and an electron is ejected. The orbital energy can be calculated from the known energy of the radiation and the measured energy of the electron lost. The following energy differences were determined for several electron transitions: ΔE2 →1 = 4.098 ×10−17 J ΔE3 →1 = 4.854 × 10−17 JΔE5 → 1 = 5.242 ×10−17 J  ΔE4 → 2 = 1.024 ×10−17 J Calculate the energy change and the wavelength of a photon emitted in the following transitions. Enter your answers in scientific notation. Use 6.626 ×10−34 J·s for Planck's constant. (a) Level 3 to 2: ______J ______m (b) Level 4 to 1: _____J_____ m (c) Level 5 to 4: _____J _____m
