CHE 131 Study Guide - Final Guide: Lone Pair, Electron Configuration, Noble Gas
Document Summary
Ionic bond electrostatic attraction of a cation for an anion covalent bond sharing of outermost electrons. Metallic bond nuclei of metal atoms surrounded by a "sea "of shared electrons. Gilbert lewis atoms form chemical bonds by sharing electrons ; acquires electron configuration of a noble gas. Octet rule atoms lose , gain or share electrons to obtain a set of 8 valence electrons. Lewis symbols (dot structures) atom surrounded by / +dots representing valence electrons. 1st 4 electrons = unpaired (top, sides , bottom) . Main group elements members of the same family have the same # of valence electrons + similar bonding capacities . Bonding pair of electrons pair of electrons shared between 2 atoms in a covalent bond single bond 2 atoms sharing 1 pair of e- Lone pair pair of e- that is not shared. 1-i :o : h or h - &. Metals lose valence electrons to achieve noble gas electron configuration.
