What is a Lewis Dot Structure?

Back

A Lewis Dot 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.

How many valence electrons does Neon (Ne) have?

Back

Neon has 8 valence electrons.

Front

What does a dot represent in a Lewis Dot Structure?

Back

A dot represents a valence electron.

Front

What is the significance of valence electrons in bonding?

Back

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

Front

How do you determine the number of bonds an atom can make?

Back

The number of bonds an atom can make is determined by the number of unpaired valence electrons.

Front

What is the correct Lewis Dot Structure for Oxygen (O)?

Back

The correct Lewis Dot Structure for Oxygen has 6 valence electrons represented as 2 pairs of dots and 2 single dots.

Front

What is the maximum number of bonds that Carbon (C) can form?

Back

Carbon can form a maximum of 4 bonds.

Front

What is a lone pair in a Lewis Dot Structure?

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 do you represent a double bond in a Lewis Dot Structure?

Back

A double bond is represented by two pairs of dots (or two lines) between two atoms.

What is the Lewis Dot Structure for a molecule of water (H2O)?

Back

The Lewis Dot Structure for water shows the Oxygen atom with 2 lone pairs and 2 single bonds to 2 Hydrogen atoms.
