Transcript of Element project! (Chlorine)

Element project! (Chlorine!)
The atomic number,mass,and symbols!

Melting Phase, Normal Phase, Boiling Point, and the Cost!
Classification,family,and period.
Chlorine's atomic number is 17. 17 is how many protons, electrons there are in chlorine.
Atomic Number!
Cl is the atomic symbol of chlorine. It shortens the word so you can remember it better.
Atomic Symbol!
35.453 units is the atomic mass for chlorine. When the atomic mass is subtracted by the atomic number then it states how many neutrons are in that element.
Atomic Mass!
-101.98 C is the boiling point of Chlorine.
Melting Point!
-34.6 C is the boiling point of chlorine.
Boiling Point!
The normal phase of chlorine is a gas.
Normal Phase!
The price for 100gs of chlorine is 15 cents.
The Cost of Chlorine!
Chlorine is a nonmetal. Chlorine is located in Group 17 of the Periodic Table. Chlorine is a gas and all gases are non-metals. You can tell if an element is non-metal by looking at the Periodic Table. Elements to the right of the stair step are non-metals.
There are 18 neutrons in chlorine. The neutrons have no charge and are in the center of the nucleus.
There are 17 protons. Protons have a positive charge and are in the nucleus.
There are 17 electrons. Electrons have a negative charge and are outside the nucleus.
The density of chlorine is 3.214 grams per cubic centimeter.
Definition: Any of the elements fluorine, chlorine, bromine, iodine, and astatine, occupying group VIIA (17) of the periodic table. They are reactive nonmetallic elements that form strongly acidic compounds with hydrogen, from which simple salts can be made.
Chlorine's period is 3.
Chlorine comes from the greek word khloros, pale green.
Chlorine was discovered in 1774 in Uppsala, Sweden. It was discovered by Carl Wilhelm Scheele.
Date and place of Discovery and who Discovered it
It was discovered in 1774 but wasn't until 1810 the Sir Humphrey Davy determined that it was an element. Also it was not found freely in nature but is derived from salt.
Extra Info
It's a toxic gas which will irritate the respiratory system. The toxic gas was used in World War 1 as an agent to kill. It has a choking smell, and inhalation causes suffocation, constriction, of the chest, tightness in the throat, and after severe exposure of the lungs they die. As little as one part per thousands in the air causes death within a few minutes.
Extra Extra Info
Sometimes they use chlorine for the pool to keep it clean but the amount of tablets they use won't hurt you.
Even More Info!
These things have chlorine in them:
water pureification
Common Uses
OR IS IT????
Hey pass the sodium chloride!!!
now the end...
