Ionization Energies; Electron Affinities (Sections)

Although the electron affinity of bromine is a negative quantity, it is positive for Kr. Use the electron configurations of the two elements to explain the difference.

Ch. 3 Quantum Theory and Electronic Structures 1. Forms of energy a. Kinetic energy – energy from motion i. Ek = 1/2m(v^2) ii. Kinetic energy = one half of the mass times velocity squared iii. Thermal energy (form of kinetic energy)– associated with the random motion of atoms and molecules b. Potential...
