Atomic Structure: Helpful Hints Cheat Sheet/Periodic Table Family Tree 4
Periodic Table 5

3. Remember!
We learned 2 ways to represent 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. Remember!
Elements are substances that are made of only one type of atom!

7. 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!

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

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

10. 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!

11. 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!

12. 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…

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

14. 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!!

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

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

17. “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

18. “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

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

34. Review: Periodic Table Family Tree

35. 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

36. 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

37. 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.

38. 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

39. 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

40. 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

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

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

Some other options might be…

46. Homework: RAFT R = Periodic Table A = Atom/Element F = Argument
