Giver or Stealer of e- G
BOTH S
N/A
Type of ion formed
CATION
ANION
Charge of ion formed +1 +2 +3
+4/-4 -3 -2 -1
Group # they bond with

4. REVIEW: The Octet Rule
Atoms give away or steal electrons in order to happy and stable with a full valence shell!
Atoms with less than 4 valence electrons tend to lose electrons.
Atoms with more than 4 valence electrons tend to gain electrons.

5. REVIEW: Ionic Vs. Covalent
Ionic = Transfer electrons; between a metal and a non-metal
Covalent = Share electrons; between 2 non- metals
Use the Periodic Table to determine if the following compounds are ionic or covalent:
SO2
CaCO3
HCl
NH3
NaOH

6. MOST ELEMENTS WANT TO COMBINE NATURALLY, BUT WHAT FORMS WHEN THEY DO?

7. It Depends… Molecule = 2 or more atoms joined
(can be the same element or more than one)
Compound = 2 or more different elements joined in a chemical reaction
Mixture = 2 or more substances combined
Solution = A type of mixture that looks the same throughout

8. Elements: Pure substances made of only one type of atom
MUST be on the Periodic Table OF ELEMENTS
Combine to form all other types of matter
Examples:
Silver
Calcium
Oxygen

9. What Does it Look Like Chemically?
Single atoms of ONE pure element
Molecules of ONE pure element

10. Compounds: Two or more elements joined during a chemical reaction
Must be combined in specific ratios
Chemical Change/Reaction
Examples:
Water
Salt
Sugar

11. What Does it Look Like Chemically?
2 or more ELEMENTS that are CHEMICALLY bonded to one another

12. Compounds are formed or separated through chemical reactions…
What is evidence that a chemical reaction is happening again?

13. Mixture
Combines 2 or more substances without producing a chemical reaction = PHYSICAL CHANGE
Different throughout = heterogeneous
Basic mixtures can be separated easily
Examples:
Soil
Fruit salad

14. What Does it Look Like Chemically?
2 or more SUBSTANCES MIXED together, but NOT chemically bonded.

15. Solution:
A type of HOMOGENOUS MIXTURE - same throughout = STILL A PHYSICAL CHANGE
Can be solids, liquids or gases
Solute- substance being dissolved
Solvent- substance doing the dissolving
Examples:
Salt water
Lemonade
Salt = Solute
Water= Solvent
Salt Water= Solution

16. What Does it Look Like Chemically?
It is also a mixture of 2 or more SUBSTANCES, but the particles will be evenly distributed throughout (homogenous)

17. Suspension: A type of HETEROGENEOUS MIXTURE – different throughout
Particles will not dissolve, (insoluble) or are suspended
Examples:
Face washes, hand sanitizer
Snow globe

18. Colloid: A type of HOMOGENEOUS SOLUTION Have an “in between” texture
Examples:
Jell-O
Pudding

19. Compounds, Mixtures, Solutions
Read the “Compounds, Mixtures, and Solutions article, and use it to answer the questions.
You may read & complete the questions with your table/group.

20. Quick Comprehension Stations
Visit each station and describe what you see using as many vocabulary terms from the article as you can…I want scientific explanations – (that means use vocabulary!!)
Each station has multiple explanations…ticket time!!

21. Homework:
NONE!!

23. WARM - UP Update your Table of Contents
Write your homework – leave it to be stamped
Take a Warm-Up from the front counter, complete both sides using your notes & your group…review/quiz each other when you finish.

Element, Compound, Mixture, Solution Warm-Up/Review 27
CSI Sarnelli: Separating a Solution 28

24. Vocab to Help with the Warm-Up
Heterogeneous = different throughout
Homogeneous = same throughout
Molecule = at least 2 atoms bonded together
Compound = at least 2 different atoms bonded together
Mixture = at least 2 substances mixed; heterogeneous
Solution = at least 2 substances mixed; type of mixture that is homogeneous

25. CSI Sarnelli: Separating a Solution
Lab Roles:
Leader – Reads the informational portions and directions for the lab
Supply Manager – manages materials
Discussion Leader – Reads the questions and begins a discussion
Speaker – designated spokesperson to answer questions for the group when they are called on
THE ENTIRE LAB SHOULD BE COMPLETED & CLEANED UP IN 20 MINUTES & YOU SHOULD BE IN YOUR SEATS READY TO DISCUSS THE RESULTS!!

26. CSI Sarnelli: Separating a Solution
Clean-Up:
Throw your chromatogram paper in the garbage.
Dump the water into your sink.
Bring your EMPTY cup & stick back to Ms. Sarnelli.
Set the graduated cylinder next to the sink where you found it.

27. In it to WIN it!
I will show you a picture and your team will have 15 seconds to figure out what it is and write it down on your white board…YOU GET ONE CHANCE!
Your answer will be one of the following:
Element = E
Compound = C
Mixture = M
Solution = S
Your team will get a token in your cup for each picture you get correct!
Goal: For your team to collect as many tokens in your cup as possible to win the candy!
