  1. A positively ELECTRIC play about particles who learn to work together despite all their differences. APE man chemistry

  2. Narrator: Protonsare positive – they have a positive charge, sunny outlook on life; protons are the nucleons that enjoy just sitting back and chillin’ Narrator: Neutrons are neutral (no charge) –these nucleons enjoy a little chilly time in the nucleus too … but, if something else interesting pops up, they make get up and move – in fact, they do! The Atomic Nucleus – he’s the man

  3. Protons & Neutrons reside (post up; chillax) in the nucleus - they are sometimes called nucleons (Nucleons: all hail the nucleons…we chill in the middle!!!! The nucleus is where big boys are.) Almost all of an atom’s mass is in its nucleus (Nucleons:all hail the nucleons…we’re massive We stay close together – we snuggle….!) Sooooooo…..what subatomic particles make up most of an atom’s mass??? The Atomic Nucleus – he’s the man

  4. Since protons and neutrons chillax in the nucleus AND they make up almost all of the atom’s mass…. • We can calculate how many neutrons are in an atom if we know the number of protons (or their nickname - atomic number) and the mass M=A+N Mass = at.# + N (remember that protons = atomic #) Watch Milli do it - now, show me you know it! In groups, work it out - be prepared teach your classmates The Atomic Nucleus – he’s the man 8 O Oxygen 16

  5. So mass # = at. # + neutrons M=A+N • How many different types of elements can we make out of our class?? • PROVE IT! • DO IT! • SHOW ME YOU KNOW IT The atomic nucleus – he’s the man

  6. Scene II Man meets ape

  7. An element’s atomic # tells you how many protons it has (protons: my atomic number is like my nickname – its what my peeps call me) A=P atomic # = # protons • If oxygen has an atomic number of 8, how many protons does it have? • Where do protons post up? • Now practice identifying atomic #s, protons (go ahead and do mass #s & names while you’re at it) • Do the practice problems on 8.5A Protons Determine Identity … in your notebook – come see me if you finish early The ape and the super-fast jellyfish 8 O Oxygen 16

  8. So… Atomic # = # protons A=P Q: what would atoms be like if they were just made of protons and neutrons? Narrator: Well, all this happy go positive nucleus vibe needs to be balance out a bit…so some really, REALLY tiny, high-energy super-fast jellyfish particles are about to come flying onto the scene (heads up electrons…) The ape and the super-fast jellyfish

  9. Well, it turns out that atoms normally have an overall neutral charge – so to balance out all those positive protons, there has to be a negative electron for each positive proton • What I’m saying is…. A=P=E Even though they are SO tiny it would take almost 2000 of them to equal the mass of 1 proton, their negative charge still balances out the proton’s positive charge (electrons: super-fast jellyfish electrons get it done! We’re tiny and far out but we get it DONE SON!) The ape and the super-fast jellyfish

  10. Earlier, I mentioned that Atomic # = # protons = # electrons remember A=P=E ???? And…. mass # = at. # + neutrons remember M=A+N Look over your notes…. The ape and the super-fast jellyfish

  11. Wait….did she say APE MAN??? APE MAN??

  12. Chemistry is so easy….an can do it!!!! A=P=E M=A+N APE MAN

  13. Turn to your neighbor and explain APE MAN chemistry to your neighbor then let your neighbor explain it to you Write a summary in your notebook – something that will help you remember this!!! Now practice applying what you know (8.5A,B Atomic Math Challenge) Think Pair Share

  14. Where do electrons THEY belong? Do they make up any of the atomic mass?? So what are they good for???? What’s up with electrons??

  15. According to current atomic theory, electrons reside in the electron cloud • For our purposes, we can consider them to be in orbitals or energy levels (remember Dr. Birdley’s atomic theory timeline cartoon – Bohr & Schrodinger models) Narrator: the electron cloud is where all the action happens – chemical bonds take place because of electrons in their super-fast jellyfish electron cloud Electrons rule!

  16. Narrator: as it happens, not all electrons are exactly alike – some are a little more adventurous than others – introducing the valiant, adventurous valance electrons and their outstanding outer orbital powers ( you should probably write that down…valence & outer orbital) • Electrons – step up…who wants to be a valance electron – you guys will move around in the outer orbital or shell • Model ( as a group, model an atom of lithium (atomic # 3) • Valence electrons: chemical reactions???? That’s all about ME!! • Valence electrons determine an elements chemical properties, including reactivity • What is reactivity?? Electrons rule!

  17. Narrator: even though it seems like chaos, electrons somehow obey certain rules • Orbital schmorbital • What is an orbital? • Narrator: its like a shell, kind of like the chocolate coating on a milky way bar or the egg shell around an egg… • Electron rules – filling orbitals • Must fill inner orbitals first • 1st orbital – 2 electrons • All other orbitals – 8 electrons Electrons rule!

  18. Lets practice making some atom models – using your classmates • Do you see how this relates to our warm-up?? • Now practice sorting electrons and those valiant, adventurous valance electrons into their outstanding outer orbitals • You will need a dry erase board, pen & wipey thingy Electrons rule!

  19. Electron rules Lets make a bohr model together • Fill inner orbitals first • Orbital 1 – 2 electrons • All others - 8 2 He 4.0 Helium Electrons rule

  20. Electron rules Now you try making a bohr model • Fill inner orbitals first • Orbital 1 – 2 electrons • All others – 8 4 Be 9.0 Beryllium Electrons rule

  21. Electron rules Now you try making a bohr model • Fill inner orbitals first • Orbital 1 – 2 electrons • All others - 8 6 C 12.0 Carbon Electrons rule

  22. Electron rules Now you try making a bohr model • Fill inner orbitals first • Orbital 1 – 2 electrons • All others - 8 10 Ne 20.2 Neon Electrons rule

  23. Electron rules Now you try making a bohr model • Fill inner orbitals first • Orbital 1 – 2 electrons • All others - 8 11 Na 23 Sodium Electrons rule

  24. Electron rules Now you try making a bohr model • Fill inner orbitals first • Orbital 1 – 2 electrons • All others - 8 13 Al 27 Aluminum Electrons rule

  25. Electron rules Now you try making a bohr model • Fill inner orbitals first • Orbital 1 – 2 electrons • All others - 8 17 Cl 35.5 Chlorine Electrons rule

  26. Electron rules Now you try making a bohr model • Fill inner orbitals first • Orbital 1 – 2 electrons • All others - 8 18 Argon 40 Argon Electrons rule

  27. A special thanks to all those who made this production possible. I’d especially like to thank the little people, the ones who REALLY make things shake - yes, valence electrons, I’m talking to YOU! Without you little guys, well..who knows? Chemistry the ape man and the superfast jellyfish
