1. Elements are pure substances made of only one kind of atom.
2. As we have learned, atoms are tiny structures found in all matter.
3. Most substances contain many different atoms.
4. It is how those atoms are arranged that determine whether you have an element, compound or mixture.
![Page 6: Elements, Compounds & Mixtures Day 2](https://reader035.fdocuments.us/reader035/viewer/2022070323/559dd8fa1a28ab4d318b47e8/html5/thumbnails/6.jpg)
1. One kind of atom2. Pure (because all particles are the
same)
3. Smallest particle to retain element’s identity
4. Separated only in nuclear reactions

1. Two or more elements and/or compounds blended together physically
2. Not pure (because all the particles are not the same)
3. Separation through distillation, magnetic, evaporation, density, or particle size
4. No set ratio

Particles look like:
Each particle keeps its own identity….they are just “blended” together
Mixture #1
Mixture #2

Examples:
Your Examples?
Heterogeneous: Different components are easy to see in this
type of blending
Homogeneous: Different components are difficult to see because they are
evenly distributed

Mixture
![Page 19: Elements, Compounds & Mixtures Day 2](https://reader035.fdocuments.us/reader035/viewer/2022070323/559dd8fa1a28ab4d318b47e8/html5/thumbnails/19.jpg)
1. A solution is a mixture where all the components blend together to look like one substance.
2. A solution is a homogeneous mixture that appears to be a single substance.
3. The solution is composed of particles of two or more substances that are distributed evenly among each other and have the same appearance and properties throughout.
![Page 20: Elements, Compounds & Mixtures Day 2](https://reader035.fdocuments.us/reader035/viewer/2022070323/559dd8fa1a28ab4d318b47e8/html5/thumbnails/20.jpg)
1. In solutions, the SOLUTE is the substance that is being dissolved and usually is the smaller quantity in the mixture.
2. The SOLVENT is the substance in the solution doing the dissolving and is usually the larger quantity in the mixture.
3. It is the SOLVENT that is doing the dissolving.
4. Go to page 144-145 in your textbook: Give examples of solutions in various states.
![Page 21: Elements, Compounds & Mixtures Day 2](https://reader035.fdocuments.us/reader035/viewer/2022070323/559dd8fa1a28ab4d318b47e8/html5/thumbnails/21.jpg)
• Homogeneous: 2 or more things evenly blended and disappear into each other.
• Solute – Smaller quantity by %• Solvent – Larger quantity by %• Solution – a homogeneous
mixture
![Page 22: Elements, Compounds & Mixtures Day 2](https://reader035.fdocuments.us/reader035/viewer/2022070323/559dd8fa1a28ab4d318b47e8/html5/thumbnails/22.jpg)
• Heterogeneous: 2 or more things put together and still can be seen.
• No set RATIO.

Have you ever put sugar into lemonade and seen the grains of sugar sink to the bottom and not dissolve?
This is because the lemonade (solution) is supersaturated. In other words, there is not enough water (solvent) to completely dissolve the sugar (solute).
Temperature and Pressure can affect saturation levels.
![Page 24: Elements, Compounds & Mixtures Day 2](https://reader035.fdocuments.us/reader035/viewer/2022070323/559dd8fa1a28ab4d318b47e8/html5/thumbnails/24.jpg)
Saturation Level What does this mean?
What does this look like? (color)
Unsaturated
Saturated
Supersaturated
•Mixture contains more solvent than solute
•Able to dissolve more solute
•Mixture contains the % of solute completely dissolved by solvent
•No able to dissolve more solute
•Mixture contains the % of solute unable to be dissolved by the % of solvent at the given temp.
High temp usually = higher solubility
