Unit 5 #2 Molecule Polarity

The electrons in a POLAR covalent molecule are shared...

• Evenly

• Unevenly

• Electrons are not shared

The electrons in a NONPOLAR covalent molecule are shared...

• Evenly

• Unevenly

• Electrons are not shared

The electrons in an ionic molecule are shared...

• Evenly

• Unevenly

• Electrons are not shared

In a polar covalent bond, the electrons spend more time and localize around the atom...

• with the Greatest Electronegativity

• with the Lowest Electronegativity

• Each atom Equally

In a nonpolar covalent bond, the electrons spend more time and localize around the atom...

• with the Greatest Electronegativity

• with the Lowest Electronegativity

• Each atom Equally

Partial charges are present in which type of bond(s)?

• Ionic

• Nonpolar Covalent

• Polar Covalent

• Both Polar Covalent and Ionic

• All covalent

Partial charges like the ones shown here are called:

• dipoles

• deltas

• ions

• magnetic poles

In this Lewis structure, the symbol above F means...

• electrons are being transferred to Fluorine

• electrons are less attracted to F than H

• electrons are more attracted to F than H

• Fluorine has formed an anion

A bond with a partially negative end and a partially positive end is:

• ionic
• polar
• non-polar
• isometric

Order the types of bonds based on the charge of their molecules. (lowest amount of charge to greatest)

• Polar Covalent --> Ionic --> Nonpolar Covalent

• Ionic --> Nonpolar Covalent --> Polar Covalent

• Nonpolar Covalent --> Polar Covalent --> Ionic
