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, 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

Noah is working on a chemistry project and needs to predict the geometry of a molecule he is studying. The molecule is shown in the picture. What is the geometry of the molecule?

• tetrahedral

• trigonal pyramidal

• trigonal planar

• angular

Aria is studying the structure of a molecule in her chemistry class. She comes across a molecule with the following structure:
