Lewis Structure/Bonding Practice

Front

What is a Lewis Structure?

Back

A Lewis Structure is 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

Valence electrons are the electrons in the outermost shell of an atom that are involved in forming bonds with other atoms.

Front

Where can hydrogen be placed in a Lewis Structure?

Back

Only as a terminal atom.

Front

What is the first step in drawing Lewis Structures?

Back

Count the number of valence electrons.

Front

How many covalent bonds does carbon need to form a full octet?

Back

4.

Front

What is a lone pair?

Back

A lone pair is a pair of valence electrons that are not shared with another atom and are not involved in bonding.

Front

How many lone pairs does CO have?

Back

2.

Front

What is the octet rule?

Back

The octet rule states that atoms tend to form bonds until they are surrounded by eight valence electrons.

Front

What is the significance of drawing bonds in Lewis Structures?

Back

Drawing bonds helps to visualize how atoms are connected in a molecule and how electrons are shared.
