Chemistry: Precision & Design, Quiz 15

In a chemistry class, Ethan and Isla are discussing a bonding situation in which electrons are shared by more than two atoms. This type of bonding is known as __________.

• delocalization

• polarization

• ionization

• localization

In a chemistry class, Abigail observed that electrons in certain molecules circulate freely through the molecule instead of being bound to a single atom or pair of atoms. These electrons are said to be __________.

• deconvoluted

• delocalized

• localized

• conjugated

Samuel is observing a water fountain where the water molecules have a symmetrical distribution of polar covalent bonds. He wonders if the water molecules will be __________ as a whole.

• nonpolar

• polar

• ionic

• metallic

In a chemistry class, Zoe is learning about different types of structures. She comes across a formula where nonbonding electrons are shown as dots around atoms and bonds are shown as lines or dots between atoms. This is known as a __________ structure.

• Lewis

• Covalent

• Ionic

• Metallic
