CH 320M Chapter Notes - Chapter 1: Electron Configuration, Linus Pauling, Carbon Group
Document Summary
Forms strong bonds with c, h, o, n, and some metals. Energy-level diagram - pictorial designation of where electrons are placed in an electron configuration. Excited state - higher energy level; when electrons are rearranged back to the ground state, energy is released. Valence shell - outermost occupied electron shell of an atom. Valence electrons - electrons in the valence shell of an atom. Lewis dot structure - symbol of an element represents the nucleus and all inner shell electrons. Atoms interact in such a way that each participating atom acquires an electron configuration that"s the same as that of the noble gas nearest it in atomic number! Ionic solids - attraction of anions and cations (ionic bond) Covalent bond - chemical bond formed by sharing electrons. Polar covalent bonds - bonds partially ionic or partially covalent. Electronegativity - measure of an atom"s attraction for the electrons it shares with another atom in a chemical bond.
