Valence Electrons
The electrons in the outer most electron shell are called
valence electrons

Electron / Lewis Dot Diagrams
An electron /
“Lewis Dot Diagram”
of an element shows the symbol of the element
surrounded by its valence electrons.

Lewis Structures
1) Find your element on the periodic table.2) Determine the number of valence electrons.3) This is how many electrons you will draw.

Lewis Structures
• Find out which group (column) your element is in.
• This will tell you the number of valence electrons your element has.
• You will only draw the valence electrons.

Groups - Review
•Each column is called a “group”•Each element in a group has the same number of electrons in their outer orbital, also known as “shells”.
Except for He, it has 2 electrons
•The electrons in the outer shell are called “valence electrons”

Lewis Structures
1) Write the element symbol.
2) Carbon is in the 4th group, so it has 4 valence electrons.
3) Starting at the right, draw 4 electrons, or dots, counter-clockwise around the element symbol.

Lewis Structures
1) Check your work.2) Using your periodic
table, check that Carbon is in the 4th group.
3) You should have 4 total electrons, or dots, drawn in for Carbon.

Electron Dot Diagrams
We use one dot for each valence electron.
