What is a Lewis Dot Structure?

Back

A diagram that shows the bonding between atoms of a molecule and the lone pairs of electrons that may exist in the molecule.

Front

What are valence electrons?

Back

Electrons in the outermost shell of an atom that are involved in forming bonds.

What is the Lewis Dot Structure for ammonia (NH3)?

Back

The nitrogen atom is in the center with three hydrogen atoms bonded to it, and one lone pair of electrons on nitrogen.

Front

What is the molecular structure of carbon dioxide (CO2)?

Back

A linear structure with a carbon atom in the center double bonded to two oxygen atoms.

What type of bond exists between carbon and nitrogen in HCN?

Back

A triple bond.

Front

What is a single bond?

Back

A chemical bond that involves the sharing of one pair of electrons between two atoms.
