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

26. 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!

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

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

29. 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

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

31. 3 Sections of the Periodic Table:  METALS = YELLOW  NONMETALS = GREEN  METALLOIDS = PINK  Use textbook pg. D20-D21…you have 5 minutes to color your copy of the periodic table 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! Color Code your Periodic Table!

32. 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!

33. 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…

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

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

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

37. Partner Up! Read about the characters from each Kingdom on the Periodic Table from the packet provided Bullet point the information for 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!!

38. 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

39. 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

40. 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.

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

42. 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

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

44. 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

45. 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
