8.1 Chemical Bonds, Lewis Symbols, and the Octet Rule.By: Chris Wemmer and Maggie Kastenhuber

Chemical BondsA chemical bond is formed whenever atoms or ions are strongly attached to one another

Types of Chemical Bonds1.Ionic Bonds-an ionic bond refers to electrostatic forces that exists between ions of opposite charge.2.Covalent Bonds- result from the sharing of electrons between two atoms. 3.Metallic Bonds- are found in metalsWork Cited:Brown and Lemay Chemistry the central scienceNew Jersey, Upper Saddle River, 2003Page 276, paragraph 2-4

Lewis SymbolsLewis symbols are simply the chemical symbols plus dots around the symbols representing the valence electrons of that chemical. Work Cited:Brown and Lemay Chemistry the central scienceNew Jersey, Upper Saddle River, 2003Page 276, paragraph 5

The Octet RuleThe rule that states that atoms will gain, lose, or share electrons in order to obtain 8 valence electrons to complete an octet. An octet of electrons consists of full s and p sub shells on an atom.An Octet can be thought of as four pairs of valence electrons arranged around the atom.
