Ionic Bonds 12/2
|What is an ionic bond?
|An ionic bond is the bond between a metal element and a non-metal element. ex. Na (metal) and Cl (non-metal)
|What is the electronegativity for ionic bonds?
|If the electronegativity is anywhere from 1.7 to 4 (look at reference table S) it is an ionic bond.
|In terms of physical properties of ions, why do ions have no conductivity?
|Ionic solids have no conductivity because there are no free moving electrons or ions unless dissolved or melted.
|What is the ONLY exception to the electronegativity rule of ionic bonds?
|Ionic bonds that have H2 as an element. The electronegativity of these bonds may be less than 1.7
|When an ionic bond is formed, which element(s) gets a sign changed?
|Both non-metal and metal elements!
|When an ionic bond is formed, which element(s) gets Lewis' electron dots?
|The non-metal element!
