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.

Front

What do Lewis Dot Structures represent?

Back

They represent the valence electrons of an atom and how they are arranged in a molecule.

Front

What is the significance of valence electrons in Lewis Dot Structures?

Back

Valence electrons determine how an atom can bond with other atoms.

Front

What is the correct Lewis Dot Structure for Sodium (Na)?

Back

A single dot representing its one valence electron.

Front

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

Back

Six dots arranged in pairs around the symbol O.

Front

What does a dot represent in a Lewis Dot Structure?

Back

A dot represents a valence electron.

Front

What is the maximum number of dots that can surround an atom in a Lewis Dot Structure?

Back

A maximum of 8 dots, representing the octet rule.

Front

What is the octet rule?

Back

The octet rule states that atoms tend to bond in such a way that they have eight electrons in their valence shell.
