Document Summary
Emission: output of radiation when an electron loses energy and is moved to a lower energy orbital. Absorption: electron gains energy and is moved to a higher energy orbital. Radiation"s frequency corresponds to the energy difference between orbitals. N = 1, 2, 3, 4 : angular-momentum quantum number (l, magnetic quantum number (ml) The ionic bond: transfer of 1 or more electrons from one atom to another, generally form between a metal and a nonmetal. Metallic elements like na, mg tend to give up electrons. Nonmetallic elements like o, n, cl, tend to accept electrons. Electron affinity (eea): the energy released when a neutral atom gains an electron to form an anion: the more negative the value. = more the atom wants to accept an electron (more energy is released upon accepting the e-: when an ionic bond is formed: Ionic bonds and the formation of ionic solids.
