Matter and Its States
Solid
A substance in which atoms move very slow.
Liquid
A substance in which atoms are paces really closely together.
Matter- Something that occupies space and can be observed by one or more senses; a physical body, a physical substance, or the universe as a whole.
Gas• A
substance in which atoms move really fast

Properties
Physical Property
Is when something can be observed without changing the identity of the substance.
Chemical Property
Is when something changes into a completely different substance.
Property- Is how you identify something based on its appearance such as its color, shape, size, density, hardness, and state.
1. Freezing Point2. Boiling Point3. Smell4. Color5. Density
1. Iron Rusting2. Bread Rising3. Gasoline Burning4. Eggs Cooking5. Milk Going Bad
Changes
Physical ChangeIs a change in form, shape or state and is easy to change back to its original state.
Chemical ChangeIs when bonds have changed, and the substance forms into a new chemical.
1. Hydrogen Burned to Oxygen
2. Cooking3. Expired Food4. Silver Tarnishing5. Burning wood
1. Solid to liquid2. Liquid to gas3. Solid to Gas4. Gas to liquid5. Liquid to Solid
Change- Is when something becomes a new thing or a different thing.
Atoms--- What is an
Atom? A unit of matter, the smallest unit of an element, having all
the characteristics of that element and
consisting of a dense. They also surround one big positively charged Nucleus.
Element--- What is an Element 1. Krypton
2. Hydrogen
3. Neon
4. Copper
5. Iron
An Element is a substance
composed of atoms having an identical number of protons in each
nucleus.
Examples
Compounds- What is a
Compound? 1. Salt
2. Plastic
3. Cotton
4. Wood
5. Steal
A compound is when something comes together
with another thing and they
combine a whole of something
else.
Examples
What is the periodic table?
How do I read/use the Periodic Table?
The periodic table is used mainly by scientists, teachers, and students to quickly locate important information about the elements. The periodic table usually tells us the symbol, atomic mass, and the atomic number.
What are trends/patterns of the Periodic Table?
In Chemistry, periodic trends patterns in the periodic table are the tendencies of certain elemental characteristics to increase or decrease as one progresses from one corner of the Periodic table of elements.
The Periodic Table is basically a chart of chemical elements. It also gives you all of the information you need to know about the element. It gives it name, atomic number, atoms, their mass, and the symbol o their name. Also it arranges them into groups/columns based on their structure and property.
Substances and Mixtures
SubstancesIs something that has mass and takes up space.
MixturesA mixture is the outcome of two or more substances mixed together
The difference between Substances and Mixtures is that a substance is just a substance, but a mixture is many substances stuck together. So basically a mixture is just one big substance.
Mixtures
Heterogeneous
Is when you can actually see the different things that are in the mixture. It isn’t mixed evenly.
Homogenous
Is when you can’t really see the stuff in the mixture. It is mixed evenly.
Examples1. Salad (Heter.)
2. Orange Juice (Homo.)3. Salt water (Heter.)
4. Water (Homo.)5. Chunky Soup (Heter.)
Solutions
Solvent
A solvent is substance that can dissolve in another substance.
Solute
Is a substance that has dissolved in another substance.
A solution is mixture of two or more substances that create a homogenous mixture, which may be a solid, liquid, gas, or even a combination of all of these.
Examples1. Iced Tea-solute
2. Sea Water-solute3. Lemonade-solute
4. Vinegar-solute5. Carbonated water-solvent
Solubility- What is
Solubility?
Solubility is the maximum amount of a solute which will dissolve in a given amount of
solvent at a fixed
temperature
