Ionic Bonds 12/2

QuestionAnswer
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!
