CF, it has a higher electronegativity
difference.

Potential energy is the _________
when a bond is formedand the atoms are
stable.
![Page 24: The Ionic bond exists between atoms that __________________ electrons](https://reader035.vdocument.in/reader035/viewer/2022062409/568146e4550346895db41e9b/html5/thumbnails/24.jpg)
Potential energy is the LOWEST
when a bond is formedand the atoms are
stable.

The bond energy is ______ when the
bond length is ______.
![Page 26: The Ionic bond exists between atoms that __________________ electrons](https://reader035.vdocument.in/reader035/viewer/2022062409/568146e4550346895db41e9b/html5/thumbnails/26.jpg)
The bond energy is LARGER when the bond length is
SMALLER.OR

Explain why CO2 is either a polar or nonpolar
molecule.
![Page 28: The Ionic bond exists between atoms that __________________ electrons](https://reader035.vdocument.in/reader035/viewer/2022062409/568146e4550346895db41e9b/html5/thumbnails/28.jpg)
Nonpolar.Even though the bonds
are each polar covalent, the oxygen are equally spaced
around carbon. This means the electrons are equally distributed
throughout the molecule and there is no dipole.
