Lewis Dot Structure Review

What are Lewis Dot Structures? What can they tell us?

• How many BONDS an atom can make

• How many VALENCE ELECTRONS an atom has

Multiple Choice

Recap: What are Valence Electrons?

• Inner most electrons

• Outer most electrons

• Electrons that only form bonds

Valence Electrons

• Are the outer most electrons of an atom

• They are usually represented by what group an atom is in

Groups

Groups go UP AND DOWN. There are 18 groups total on the periodic table. Groups have names known as families

What do group numbers tell us?

Each group number tells us the number of valence electrons, which tell us the Lewis Dot Structure of an atom
