These diagrams are made with the symbol of an element surrounded by dots that represent pairs of electrons

- OR - This model represents the valence electrons in an element:

• Bohr Model

• Lewis Dot Structures

• Orbital Maps

• Periodic Table

What is the first thing you need to do when drawing Lewis Structures?

• Draw your bonds

• Count the number of valence electrons

• Subtract to make the valence number even

• Add to make the valence number even

What is the goal of the Lewis Dot Structure?

• To determine the electron position

• To show an element's valence electrons and bonding capabilities

• To find the atomic mass of an element

• To search for the number of electrons in an individual atom

These electrons are in the outermost energy level of an atom - you can also decipher how many of these electrons orbit atoms based on their Periodic Table group number:

• Neutrons

• Protons

• Ions

• Valence electrons

The way that atoms gain or shed electrons in order to maintain a steady valence orbit is known as:

• The Elite Eight

• The Secure Shell

• The Octet Rule

• The Eight is Great Rule
