Elements, Compounds & Mixtures
![Page 2: Elements, Compounds & Mixtures. GOAL To tell the difference between elements, compounds and mixtures and to give examples of each](https://reader035.vdocuments.net/reader035/viewer/2022062321/56649d9d5503460f94a863e4/html5/thumbnails/2.jpg)
GOAL
• To tell the difference between elements, compounds and mixtures and to give examples of each
![Page 3: Elements, Compounds & Mixtures. GOAL To tell the difference between elements, compounds and mixtures and to give examples of each](https://reader035.vdocuments.net/reader035/viewer/2022062321/56649d9d5503460f94a863e4/html5/thumbnails/3.jpg)
Matter• Matter is anything that has
mass and takes up space.
• Matter is made up of many different things:

Substance
A substance is a single kind of matter that has a specific composition and a specific set of properties - for example, color, melting point, texture . . .

Physical Properties
Physical Properties are characteristics of substances that can be observed without changing it into another substance.
Examples: freezing or melting density hardness color

Chemical Properties
Chemical Properties are characteristics of pure substances that describe their ability to change in to different substances.

Chemical Properties
Examples:
Does it burn? (Flammability)Does it combine with oxygen?(Iron does and forms rust.)
What will the substance react with?

Types of substances
• Elements • Simplest, pure substance, one type of atom present– O2, Na, Fe, N2

Elements
There are over 100 elements in the periodic table. Elements all have unique symbols:
Hydrogen: HLithium : LiOxygen : O2
Neon : Ne

Types of substances
• Compound • 1. Made of several different atoms (combined by chemical reaction)– Salt- NaCl– Sugar- C6H12O6
• 2. Different properties from the elements that make them up
![Page 12: Elements, Compounds & Mixtures. GOAL To tell the difference between elements, compounds and mixtures and to give examples of each](https://reader035.vdocuments.net/reader035/viewer/2022062321/56649d9d5503460f94a863e4/html5/thumbnails/12.jpg)
Types of substances
• Mixtures • 1. Made of more than one kind of molecule (many compounds)
• 2. Can be separated or pulled apart by physically (they are NOT chemically combined)
• 3. 2 types:– Heterogeneous– Homogeneous
![Page 13: Elements, Compounds & Mixtures. GOAL To tell the difference between elements, compounds and mixtures and to give examples of each](https://reader035.vdocuments.net/reader035/viewer/2022062321/56649d9d5503460f94a863e4/html5/thumbnails/13.jpg)
Heterogeneous Mixtures
• You can see the different parts.
• Examples:• Salad• Soil• Bowl of Mixed Nuts
![Page 14: Elements, Compounds & Mixtures. GOAL To tell the difference between elements, compounds and mixtures and to give examples of each](https://reader035.vdocuments.net/reader035/viewer/2022062321/56649d9d5503460f94a863e4/html5/thumbnails/14.jpg)
Types of substances
• Heterogeneous Mixtures
• 1. Not the same throughout
• 2. Large easily seen particles that can be separated out
• 3. Heterogeneous liquid mixtures known as suspensions– Settles after standing
• 4. Tacos, salad, italian dressing, pebble/sand mixture

Homogeneous Mixture
• They are so evenly mixed, you can not see the individual parts.
• Examples:• Salt dissolved in water• Brass is a mixture of
copper and zinc

Types of substances
• Homogeneous Mixtures
• 1. Appears same throughout• 2. Well mixed• 3. Won’t settle upon standing,• 4. Tiny unrecognizable particles
–Solutions are homogeneous mixtures
