  1. Periodic Table of Elements 8th Grade Science

  2. WARM UP: • Write homework – leave it out to be stamped • Put your science brochure in the basket. MAKE SURE YOUR NAME & BLOCK are on it! • Update Table of Contents • On page 8, number 1-10 leaving a few lines between each…then REVIEW YOUR NOTES!

  3. Remember! • We have learned there are 2 ways to represent an atom of an element: Sodium

  4. Lets try our math a different way today! Atomic # = __________ Atomic Mass = ________ # of Protons = _________ # of Neutrons = ________ # of Electrons = ________ Element Name: ________ Element Symbol: ______

  5. One More Time… Atomic # = __________ Atomic Mass = ________ # of Protons = _________ # of Neutrons = ________ # of Electrons = ________ Element Name: ________ Element Symbol: ______

  6. Ion Review & Quiz

  7. Atomic #: __________ Atomic Mass: _______ # of Protons: _______ # of Neutrons: ______ # of Electrons:______ Name:_________ Symbol:________ #1

  8. #2 Atomic #: __________ Atomic Mass: _______ # of Protons: _______ # of Neutrons: ______ # of Electrons:______ Name:_________ Symbol:________

  9. #3 Atomic #: __________ Atomic Mass: _______ # of Protons: _______ # of Neutrons: ______ # of Electrons:______ Name:__________ Symbol:_________

  10. #4 Atoms of the same element with different numbers of neutrons are called ____________.

  11. #5 If an atom loses or gains an electron, it becomes an ____________. Gaining an electron results in a negative _________, losing an electron results in a positive _________

  12. Atomic #: __________ Atomic Mass: _______ # of Protons: _______ # of Neutrons: ______ # of Electrons:______ Element:__________ Symbol:__________ #6

  13. Atomic #: __________ Atomic Mass: _______ # of Protons: _______ # of Neutrons: ______ # of Electrons:______ Element:_________ Symbol:__________ #7

  14. #8 Changing the number of protons results in a ___________________________. For example: - one proton = + one proton = ___________ ____________ ___________

  15. #9 Atomic #: __________ Atomic Mass: _______ # of Protons: _______ # of Neutrons: ______ # of Electrons:______ Element:_________ Symbol:_________

  16. #10 • Draw the Bohr diagrams for Beryllium (Be) and Argon (Ar) • Are they happy and stable?

  17. Isotope Review & Quiz

  18. “Pop” Quiz Time! • Close your notebook • Open the textbook to page D-20 to use the Periodic Table…this is the ONLY thing your are allowed to use! • When you are finished, please bringyour paper up to me and start working on your Atoms Family Album!

  19. CLASSWORK/HOMEWORK • Create your own “Atoms Family Album” • Fold the album together in a way that you would like, but it must have room for all 5 family members • You must have a representative drawing and a description of the following family members: PROTON, NEUTRON & ELECTRON, ION, ISOTOPE

  20. WARM UP: • No Homework! • Put your “Atoms Family Album” in the basket. MAKE SURE YOUR NAME & BLOCK are on it! • Update Table of Contents • Start the Skill & Drill Practice Charts Warm-Up

  21. Warm-Up/Review: • Skill & Drill Practice Charts • Introducing Ions to the Mix!

  22. Basic Neutral Atoms

  23. Adding Ions to the Mix

  24. Remember! • Elements are substances that are made of only one type of atom!

  25. Remember! • Each element alone is like an ingredient in a recipe…we combine different elements together to make all the different types of matter in the universe!

  26. Guess What????? • It’s time to get your very own copy of your new best friend…The Periodic Table!

  27. Trends of The Periodic Table • Organizes all of the elements based on properties and atomic number of the elements • Originally organized by Dmitri Mendeleev

  28. Reading the periodic table • Period – Row across the periodic table • Tells you how many electron shells there are • As you move across, the atomic radius gets bigger

  29. Reading the periodic table - • Group – Column going down the periodic table • how many valence electrons there are…but there is a trick

  30. Color Code your Periodic Table! • 3 Sections of the Periodic Table: • METALS = YELLOW • NONMETALS = GREEN • METALLOIDS = PINK • Use textbook pg. D20-D21…you have 5 minutes to color and create a key! • You can use different colors, but you must use the same pattern you see in the book! • Do NOT use markers!

  31. Knights of the Periodic Table • Once upon a time in a land far, far away, there were 3 kingdoms. Each kingdom had it’s own royal “families,” and each family member had their own very unique personality. Like in every family, some of them were very well behaved…and others were quite naughty, but one thing is for sure, every time the family members from different kingdoms came into contact with each other it caused quite a reaction!

  32. Knights of the Periodic Table Analogy There are 3 sections or “Kingdoms” of the Periodic Table: • Metal Kingdom = • Metalloid Kingdom = • Nonmetal Kingdom = Each character is meant to represent a different group and their unique properties…

  33. What’s Up With Hydrogen? • Hydrogen the Court Jester • Different from any of the other elements • Nonmetal • Has 0 neutrons

  34. The Metal “Kingdom” • Reactive Metals • Group 1 – Alkali metals • Group 2 – Alkaline metals • Non-reactive Metals • Groups 3-12 are the Transition Metals

  35. The Non-Metal “Kingdom” • Non-metals • Group 17 – Halogens • Very reactive gases • Group 18 – Noble Gases • Non reactive gases Noble Gases Halogens

  36. Partner Up! • Read about the characters from each Kingdom on the Periodic Table from the packet provided • Bullet point the informationfor each character on the lines provided • This is a way for you to make connections and remember information about each of the Kingdoms and groups on the Periodic Table, so make it count because you will need this for the rest of the unit!!

  37. Prince AL of the Metal Kingdom • Character Description: Prince Al is very aggressive. He fights anyone and everyone because he feels like he is missing something and wants to feel complete. • Periodic Table Connection: • Represent Group 1: Alkali Metals • Most reactive metals • 1 valence electron, always looking to bond to be “happy” • Ex: Foods, medicines, fertilizers, lithium batteries

  38. Prince ALAN of the metal Kingdom • Character Description: Prince Alan is not as aggressive as his brother Al, but still likes to fight because he also feels he is missing something, and wants someone to bond with. • Periodic Table Connection: • Represents Group 2: Alkaline Metals • Reactive metal but not as reactive as Alkali Metals • Have 2 valence electrons, always looking to bond to be “happy” • Ex: cancer treatment & medical imaging, fireworks/flares

  39. Prince TRAVIS of the metal Kingdom • Character Description: Travis, unlike his brothers is always constant and rarely changes. He is laid back and instead he focuses on his job as a handyman – fixing problems rather than creating them! • Periodic Table Connection: • Represent Groups 3-12: Transition Metals • Stable & do not react with most elements • Malleable, ductile & good conductors • Ex: copper, gold, silver- used to make tools, wires, household items, jewelry etc.

  40. The Metalloid “Kingdom” • Metalloids - Found on the zig-zag steps • Have properties of metals and nonmetals

  41. Queen CYBIL of the Metalloid Kingdom • Character Description: Cybil has a split-personality: “girly girl” AND “tomboy.” She changes her personality based on who she is around – Cybil is “two-faced” • Periodic Table Connection: • Have characteristics of both metals and nonmetals • Reacts differently depending on who they react with • Ex: silicon- a semiconductor used in electronics

  42. The Non-Metal “Kingdom” • Non-Metals • Group 17 – Halogens • Very reactive gases • Group 18 – Noble Gases • Non reactive gases Noble Gases Halogens

  43. Princess DARLENE of the non-metal Kingdom • Character Description: Darlene is a drama queen because she wants to be “perfect” like her sister Nora the Noble Princess. Darlene loves to spend time with Al of the metal kingdom • Periodic Table Connection: • Represents Group 17: Halogens • Reactive nonmetals • Have 7 electrons in their valence shell…so close to being “happy” • Ex: detergents & cleaners, halogen lightbulbs

  44. Princess NORA of the non-metal kingdom • Character Description: Nora the noble princess is the perfect proper princess. She avoids drama by sticking to herself unless she is needed to help prevent drama among others. • Periodic Table Connection: • Represents Group 18: Noble Gases • Do not react with other elements because their valence shell is full • Ex: neon in signs

  45. Questions?

  46. WARM UP: • Write your homework – leave it out to be stamped! • Update Table of Contents

  47. REVIEW: Last time I gave you 2 “shortcuts” for the Periodic Table…what were they? • Period (row) = ? • Group (column) = ? HINT:

  48. Lewis Dot Finding # of Valence Electrons: Bohr Diagram 2 types of diagrams to show electrons Shows ALL electrons • Shows ONLY valence electrons O
