Periodic Table of Elements 8th Grade Science

WARM UP: Update your Table of Contents Write your homework – leave it out to be stamped – vocab cards out to be checked Put your Atom’s Family Album in the basket! Complete the “Atomic Structure: Helpful Hints Cheat Sheet” Date Session # Activity Page 12/6 3 Atomic Structure: Helpful Hints Cheat Sheet/Periodic Table Family Tree 4 Periodic Table 5

Remember! We learned 2 ways to represent an element: Sodium

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

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

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

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!

The Periodic Table Organizes all of the elements based on properties and atomic number of the elements

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

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!

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!

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…

Knights of the Periodic Table Analogy Hydrogen the Court Jester Different from any of the other elements Nonmetal Has 0 neutrons

Partner Up! Read about the characters from each Kingdom on the Periodic Table from the packet provided Fill in the “Periodic Table Family Tree” for each character 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!!

Reading the periodic table Period – Row across the periodic table (tells you how many electron shells there are)

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

“Kingdoms” of the Periodic Table Metal – Left side of the periodic table Broken in to two regions: Reactive metals Group 1 – Alkali Group 2 – Alkaline Nonreactive metals Groups 3-12 are the Transition metals

“Kingdoms” of the Periodic Table Nonmetals – right side of the periodic table Two groups Group 17 - Halogens Very reactive gases Group 18 -Noble Gases Nonreactive gases Noble Gases Halogens

Kingdoms of the Periodic Table Metalloids - Found on the zig-zag steps Have properties of metals and nonmetals

Review: Periodic Table Family Tree

AL Kingdom: Metal Character Description: Periodic Table Connection: very aggressive Fights anyone and everyone Feels like he is missing something and wants to feel complete Periodic Table Connection: Group 1: Alkali Metals Most reactive metals Missing 1 electron so always want to bond with another element  

ALAN Kingdom: Metal Character Description: Periodic Table Connection: Not as aggressive as brother, Al, but likes to fight Feels like he is missing something and always looking for someone to bond with Periodic Table Connection: Group 2: Alkaline Metals Reactive metal but not as reactive as Alkali Metals

TRAVIS Kingdom: Metal Character Description: always constant and rarely changes Laid back and does not react with other people Handyman that can fix things Periodic Table Connection: Transition Metals Stable & do not react with most elements Ex: copper, gold, silver- used to make tools, wires, household items, jewelry etc.  

CYBIL Kingdom: Metalloid Character Description: Split-personality: “girly girl” AND “tomboy” Changes personalities based on who she is around – “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

DARLENE the Drama Queen Kingdom: Nonmetal Character Description: wants to be perfect like her sister Nora the Noble Princess Loves to spend time with Al and Alan Periodic Table Connection: Group 17: Halogens reactive nonmetals Have 7 electrons in outer shell but want 8 like the noble gases

NORA the Noble Princess Kingdom: Nonmetal Character Description: perfect princess avoids drama and sticks to herself Periodic Table Connection: Group 18: Noble Gases Do not react with other elements because their outer electron shell is full Ex: neon

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

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

Whiteboard Practice - Bohr Diagrams! He S H Al C K
