Isotope Review & Quiz

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

“Pop” Quiz Time!Close your notebookOpen 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 bring your paper up to me and start working on your Atoms Family Album!

WARM UP:Write your homework – leave it to be stamped!Put your Science Brochure & “Atoms Family

Album” in the basket. MAKE SURE YOUR NAME & BLOCK are on both!

Guess What?????It’s time to get

your very own copy of your new best friend…The Periodic Table!

Trends of The Periodic Table(you should be taking these notes on page 11)Organizes all of the elements based on

properties and atomic number of the elements

Originally organized by Dmitri Mendeleev

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

Reading the periodic table - Group = Column going down the periodic table

how many valence electrons there are…but there is a trick

3 Sections of the Periodic Table: METALS = YELLOWNONMETALS = GREENMETALLOIDS = 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!

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!

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…

What’s Up With Hydrogen?

(Keep copying on page 11)Hydrogen the Court Jester Different from any of the other elements Nonmetal Has 0 neutrons

The Metal “Kingdom”

Reactive Metals• Alkali metals – Group 1

The Metal “Kingdom”

Reactive Metals• Alkaline metals – Group 2

The Metal “Kingdom”

Non-reactive Metals• Transition Metals - Groups 3-12

The Metalloid “Kingdom”

Metalloids - Found on the zig-zag stepsHave properties of metals and

nonmetals

The Non-Metal “Kingdom”

Non-metalsHalogens – Group 17

Very reactive gases

The Non-Metal “Kingdom”

Non-metals Noble Gases – Group 18

Non reactive gases

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!!

Homework: RAFTR = RoleA = AudienceF = FormatT = Topic

For example…I used my “Knights of the Periodic Table” fairytale analogy to teach you!

R = TeacherA = My studentsF = Fairytale

analogyT = The trends of

the Periodic Table

Some other options might be…

Homework: RAFTR = Periodic TableA = Atom/Element F = Letter that

explains or arguesT = Why the

atom/element is not allowed to move to another kingdom

R = SongwriterA = TeenagersF = Rap/Song T = War between the

Kingdoms

Homework: RAFTR = Game

ManufacturerA = Middle School

Students F = Board Game or

Card Game T = Traveling

through the Periodic Table

R = Advertising Agency

A = “Unhappy” atoms F = Dating/Bonding

advertisement/websiteT = Importance of

Valence electrons – Bohr diagrams

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…

The Metal “Kingdom”

Reactive Metals• Alkali metals – Group 1

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

 

The Metal “Kingdom”

Reactive Metals• Alkaline metals – Group 2

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

The Metal “Kingdom”

Non-reactive Metals• Transition Metals - Groups 3-12

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. 

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

The Non-Metal “Kingdom”

Non-metalsHalogens – Group 17

Very reactive 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 light bulbs

The Non-Metal “Kingdom”

Non-metals Noble Gases – Group 18

Non reactive gases

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
