U5 Review: Molecule Polarity

If the atoms that share electrons have an unequal attraction for the electrons, the bond is called

• nonpolar

• polar

• ionic

• dipole

Nonpolar covalent bonds are not common because

• ions always form when atoms join

• dipoles are rare in nature

• one atom usually attracts electrons more strongly than the other

• the electrons usually remain equally distant from both atoms

A neutral group of atoms held together by covalent bonds is a

• molecular formula

• chemical formula

• molecule

• monoatomic ion

What is placed between resonance structures to indicate resonance?

• double-headed arrow

• single-headed arrow

• dots

• Lewis structure

If two covalently bonded atoms are identical, the bond is

• coordinate covalent

• polar covalent

• dipole covalent

• nonpolar covalent

What are shared in a covalent bond?

• ions

• Lewis structures

• dipoles

• electrons

The following molecules contain polar bonds. The only polar molecule is

• CCl₄

• CO₂

• NH₃

• CH₄

What type of bond is shown in this image?

• Ionic
• Polar Covalent
• Nonpolar Covalent
• Van der Waals Force

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 a cation
