Front

How many valence electrons are represented in a Lewis Dot Diagram with 5 dots?

Back

5 valence electrons.

Front

What is the significance of valence electrons?

Back

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

Front

What is the difference between a Bohr Diagram and a Lewis Dot Diagram?

Back

A Bohr Diagram shows all electrons in their energy levels, while a Lewis Dot Diagram only shows valence electrons.

Front

How do you determine the number of valence electrons from the periodic table?

Back

The group number of the element indicates the number of valence electrons.
