Ionic Bonds 12/2
Question | Answer |
---|---|
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! |
