Remember! Elements are substances that are made
of only one type of atom!
![Page 26: Periodic Table of Elements](https://reader035.fdocuments.in/reader035/viewer/2022062810/56815dfd550346895dcc3a6e/html5/thumbnails/26.jpg)
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!
![Page 27: Periodic Table of Elements](https://reader035.fdocuments.in/reader035/viewer/2022062810/56815dfd550346895dcc3a6e/html5/thumbnails/27.jpg)
Guess What?????It’s time to get
your very own copy of your new best friend…The Periodic Table!
![Page 28: Periodic Table of Elements](https://reader035.fdocuments.in/reader035/viewer/2022062810/56815dfd550346895dcc3a6e/html5/thumbnails/28.jpg)
Trends of The Periodic TableOrganizes all of the elements based on
properties and atomic number of the elements
Originally organized by Dmitri Mendeleev
![Page 29: Periodic Table of Elements](https://reader035.fdocuments.in/reader035/viewer/2022062810/56815dfd550346895dcc3a6e/html5/thumbnails/29.jpg)
Reading the periodic table
Period – Row across the periodic tableTells you how many electron shells there are As you move across, the atomic radius gets bigger
![Page 30: Periodic Table of Elements](https://reader035.fdocuments.in/reader035/viewer/2022062810/56815dfd550346895dcc3a6e/html5/thumbnails/30.jpg)
Reading the periodic table - Group – Column going down the periodic table
how many valence electrons there are…but there is a trick
![Page 31: Periodic Table of Elements](https://reader035.fdocuments.in/reader035/viewer/2022062810/56815dfd550346895dcc3a6e/html5/thumbnails/31.jpg)
3 Sections of the Periodic Table: METALS = YELLOWNONMETALS = GREENMETALLOIDS = 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!
Color Code your Periodic Table!

Knights of the Periodic TableOnce 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!
![Page 33: Periodic Table of Elements](https://reader035.fdocuments.in/reader035/viewer/2022062810/56815dfd550346895dcc3a6e/html5/thumbnails/33.jpg)
Knights of the Periodic Table
AnalogyThere 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…

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!!

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 MetalsMost reactive metals 1 valence electron, always looking to bond to be “happy”Ex: Foods, medicines, fertilizers, lithium batteries
![Page 39: Periodic Table of Elements](https://reader035.fdocuments.in/reader035/viewer/2022062810/56815dfd550346895dcc3a6e/html5/thumbnails/39.jpg)
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 MetalsReactive metal but not as reactive as Alkali MetalsHave 2 valence electrons, always looking to bond to be
“happy”Ex: cancer treatment & medical imaging, fireworks/flares

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
MetalsStable & do not react with most elementsMalleable, ductile & good conductorsEx: copper, gold, silver- used to make
tools, wires, household items, jewelry etc.
![Page 41: Periodic Table of Elements](https://reader035.fdocuments.in/reader035/viewer/2022062810/56815dfd550346895dcc3a6e/html5/thumbnails/41.jpg)
The Metalloid “Kingdom”
Metalloids - Found on the zig-zag stepsHave properties of metals and
nonmetals

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 nonmetalsReacts differently depending on who
they react withEx: silicon- a semiconductor used in
electronics
![Page 43: Periodic Table of Elements](https://reader035.fdocuments.in/reader035/viewer/2022062810/56815dfd550346895dcc3a6e/html5/thumbnails/43.jpg)

Non reactive gases
Halogens
Noble Gases

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: HalogensReactive nonmetalsHave 7 electrons in their valence shell…so close to
being “happy”Ex: detergents & cleaners, halogen lightbulbs
![Page 45: Periodic Table of Elements](https://reader035.fdocuments.in/reader035/viewer/2022062810/56815dfd550346895dcc3a6e/html5/thumbnails/45.jpg)
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 GasesDo not react with other elements because their
valence shell is full Ex: neon in signs
