Lewis Structures

Find your element on the periodic table.

Determine the number of valence electrons.

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.

www.chem4kids.com

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”

www.chem4kids.com

Lewis Structures

Write the element symbol.

Carbon is in the 4th group, so it has 4 valence electrons.

Starting at the right, draw 4 electrons, or dots, counter-clockwise around the element symbol.

Lewis Structures

Check your work.

Using your periodic table, check that Carbon is in the 4th group.

You should have 4 total electrons, or dots, drawn in for Carbon.

Lewis Structures Name:

• Lewis structures, or dot diagrams, are a simplified way to show how the valence electrons are arranged in the outer shell. This is where the chemical reactions take place. Atoms will either share or give away these electrons to form bonds.

• Using your periodic table, determine the number of valence electrons for each element. • Draw a dot to represent each valence electron around the element symbol. • Follow the pattern below starting with position number 1.
