**Let’s Talk About Valence Electrons**

What are Valence Electrons? What’s the Octet Rule? Electrons in the outer most shell Determine elements chemical properties Atoms gain, lose, or share electrons in order to have 8 valence electrons How do valence electrons effect an elements reactivity?

**Charged Atoms What is an**

ion? How is the Octet Rule related to ions? An atom or bonded group of atoms with positive (+) or (-) charge Atoms gain or lose electrons to try to have 8 valence electrons They want to be like Noble Gases

27
**Let’s Talk About Valence Electrons**

Elements on the left side of the Periodic Table (Groups IA, IIA, IIIA) will tend to lose valence electrons. End up with a Positive charge= Cations Elements on the right side of the Periodic Table (Groups VA, VIA, VIIA) will tend to gain valence electrons End up with a Negative charge= Anions How do atoms lose and gain electrons? What are Cations and Anions Cations and Anions attract each other
