·Plasma
Definition: Plasma is a distinct phase of matter, separate from the traditional solids, liquids, and gases.
It is a collection of charged particles that respond strongly and collectively to electromagnetic fields, taking the form of gas-like clouds or ion beams.
Since the particles in plasma are electrically charged (generally by being stripped of electrons), it is frequently described as an "ionized gas."
Plasma was first identified (as "radiant mattter") by Sir William Crookes in 1879. Sir J.J. Thomson identified the nature of the matter in 1897.
It was Irving Langmuir who assigned the term "plasma" in 1928.
It is odd to consider that plasma is actually the most common phase of matter, especially since it was the last one discovered.
Flame, lightning, interstellar nebulae, stars, and even the empty vastness of space are all examples of the plasma state of matter.

Classification of Matter
Pure Substances:
Have a definite and consistent composition
They cannot be broken down into anything else byphysical or chemical means.
Elements and Compounds
Classification of Matter
Pure Substances: elements and compounds
1. Elements - Simplest form of pure substance.
- Consist of only one type of atom
- On periodic table ~ have a symbol
EX. oxygen, iron, carbon, silver
Solids, malleable, ductile, good conductors, mercury the only liquid at room temperature. Largest group of elements.
2. Nonmetals Solids and gases, brittle, poor conductors. Bromine the only liquid at room temperature.
3. Metalloids Share properties of both. Smallest group of elements.
Three Types of Elements1.
Metals
Properties of Metals
1. Metals are good conductors of heat and electricity.2. Metals are shiny, metallic luster.3. Metals are ductile (can be stretched into thin wires).4. Metals are malleable (can be pounded into sheets)5. A chemical property of metal is its reaction with water which results in corrosion.

1.The elements of- Aluminum, Iron, Oxygen, and Silicon make up about 88% of the earth's solid surface.2.Water on the surface and in the air as clouds and fog is made up of hydrogen and oxygen.3.The air is 99% nitrogen and oxygen.4.Hydrogen, oxygen, and carbon make up 97% of a person.5.Thus almost everything you see in this picture is made up of just six elements.
Fun Facts
Worksheet: What Are The Symbols For The Elements?Symbols are signs that stand for something else. Here are some symbols that you may know: $ % @ & #. What does each one stand for?
There is a symbol for each of the 106 chemical elements. There are 106 symbols because there are 106 elements. The symbols for the elements are the same all over the world. It makes no difference what country you are in or what language you speak; the chemical symbols are the same.
I. HOW DO THE ELEMENTS GET THEIR SYMBOLS?1. Often the first letter of the element’s name is the symbol for that element.2. The name of the element may begin with a letter that is already the symbol for another element. In that case, it may be the first and second letters that are used or the first letter and another letter in the name may be used to make the symbol.3. The first letter of the symbol is always capitalized. The second letter (if used) is always a lowercase letter.4. A few elements are named after places or famous scientists.
II. HOW ELEMENTS ARE NAMEDStudy the Periodic Table of Elements that you were given. Do any of the names of the elements sound familiar? They should. Some elements have ancient names of Latin and Greek origins; but many other were named for famous scientists, countries, planets, etc. With a copy of the Periodic Table before you, answer the following questions.1. There are several elements named for famous scientists. Can you find three? __________________ , __________________ , and _____________________2. There are four elements named for the planets. Can you find all four of them? __________________ , ___________________ , ___________________ , and ____________________3. There is one element named for a city in the United States and another for the state of that city. Can you find the element named for the city and the element named for the state? (Hint: They are next to each other on the table.) ___________________ and ___________________4. There are two elements named for large regions which include several countries. Do you know what these elements are called? ________________ and ________________5. Element numbers 39, 65, 68, and 70 were all named for the same city, Ytterby, Sweden. What are the names of these elements? __________________ , ___________________ , ___________________ , and ____________________6. The ancient name for France was Gaul, and the ancient name for Russia was Ruthernia. Can you find the elements named for these ancient lands? _____________________ and _______________________7.

Characteristics of Ionic compoundsSome important characteristics of ionic compounds are as follows.1. Ionic compounds are hard and rigid due to strong forces of attraction between the oppositely charged ions. 2. Ionic compounds have high melting and boiling points, again due to strong forces of attraction between the ions.3. Ionic compounds dissolve easily in water.4. Solid Ionic compounds do not conduct electricity because their constituent ions are fixed in their positions. But, when melted or dissolved in water, they conduct electricity because the ions become free in a solution.5. Ionic compounds are crystalline due to the orderly distribution of ions in them. This gives characteristic geometrical shapes to the ionic compounds. Precipitates
Binary Ionic CompoundsCombination of a metal and nonmetal
Ionic Bond ~ Bond between metals and nonmetalsbonding is due to atoms that lose or gain
electronsThe metal atoms lose electrons ~ they are called *cationsPositive ions ~ Positive charge ( have more protons than electrons)
The nonmetals atoms gain electrons ~ they are called anionsNegative ions ~ Negative charge ( have more electrons than protons
***The charge is neutral when the atoms combine = ionic compound
Write the name of the first element (metal) poisitive ion (cation)
Write the root of the second element (nonmetal) negative ion (anion) add ide

Classification of Matter
Mixtures
Two or more substances that are not chemically combinedwith each other- they are mixed together.Composition may vary
The “things” in a mixture keep their individual properties.
May be separated by physical means
Distillation (liquid is boiled to produce a vapor that is condensed again to a
liquid)Filtering (separating contents)
Classify samples and sets of matter as a solution, colloid or suspension based on the application of characteristic properties: particle size, “settling out” of one or more components, and interaction with light (Tyndall Effect).

Solutions and SolubilityParts of a Solution
1. Solute
What is being dissloved
2. SolventWhat is doing the
dissolving
Solubility
The maximum amount of solute a solvent can dissolve at a certain temperature
Expressed as grams of solute in 100 grams of solvent (usually water)
g of solute
100 grams of water
chem4kids.com
http://www.chem4kids.com/files/matter_solution.html
Solutions and Solubility
1. Unsaturated Solutions
can dissolve more solute at a given temperaturecontains less than the maximum amount of solute
Contains the maximum amount of solute at a given temperaturecannot dissolve any more
2. Saturated Solutions
Supersaturated SolutionsContains more solute at a certain temperature because it has been heated
Effect of Temperature on Solubility
Solubility·depends on temperature·of most solids increases as temperature increases·of gases decreases as temperature increases
Solubility Curve
Solubility and Pressure
Henry’s law states: ·the solubility of a gas in a liquid is directly related to the pressure of that gas above the liquid·at higher pressures, more gas molecules dissolve in the liquid
At 40 °C, the solubility of KBr is 80 g/100 g of H2O.Identify the following solutions as either (S) saturated or (U) unsaturated. Explain.A. 60 g KBr added to 100 g of water at 40 °C.B. 200 g KBr added to 200 g of water at 40 °C.C. 25 g KBr added to 50 g of water at 40 °C.
Learning Check
Increasing Solubility
1. grind solute increase surface area
2. increase temperature3. stir solute
Concentration Diluted
Classification of Matter
2. Heterogeneous Mixtures ~ SuspensionsNot uniform in
composition
EX. oil and vinegar, raw milk
- has physically distinct parts with different properties - non-uniform throughout.
- individual components can be seen
- beef stew, tossed salad, chex mix, nuts and bolts
2. Heterogeneous Mixtures ~ Suspensions
Classification of Matter
EX. oil and vinegar, raw milk, muddy water, paint
Suspensions
Heterogeneous mixtures that separate into layershas to be shaken or stirred to get a uniformity in it.
