Week Agenda Monday: Bohr Model Tuesday: Bohr Model with Ions Wednesday: Constructing an Atom Activity Thursday: Happy Thanksgiving! No School! Friday: No School!
Group Norms • Be Engaged! (Off Cell Phones, Heads Up, Answering Questions) • Mistakes are Welcome! • Be Respectful (Speak politely to peers and teachers!) • Use Time Preciously! (Be Efficient, Keep Up)
Objective: • S.W.B.A.T apply the bohr model to charged atoms (ions) Homework: • BOHR MODEL with ions PROBLEM SET ANNOUNCEMENTS QUIZZES MUST BE FINISHED OR MADE UP BY TUESDAY AFTER SCHOOL!! IF I DON’T HAVE A SCIENCE FAIR IDEA BY WEDNESDAY, I WILL ASSIGN YOU A PROJECT ALL HOMEWORK MUST BE WRITTEN IN AGENDA BOOKS. MAKE SURE YOU HAVE YOURS EVERY DAY!

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?
Exit Ticket • Silently Complete your Exit Ticket/Reflection. You have 5 minutes • When finished raise your hand for Ms. Durrette to collect it • Keep your Cornell Notes out, we have a few more notes to take!
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
Let’s Talk About Valence Electrons • How do atoms lose and gain electrons? • What are Cations and Anions • Elements on the leftside of the Periodic Table (Groups IA, IIA, IIIA) will tend to lose valence electrons. • End up with a Positive charge= Cations • Elements on the rightside of the Periodic Table (Groups VA, VIA, VIIA) will tend to gain valence electrons • End up with a Negative charge= Anions Cations and Anions attract each other
