2. Chlorine The elements name is chlorine The atomic number is 17
The atomic symbol is Cl

3. History
It was discovered in 1774 by Scheele, who thought it contained oxygen, chlorine was named in 1810 by Davey who decided it was an element.
It was discovered by Carl Wilhelm Scheele
It name came from the Greek word khlôros which means green

4. Uses
In nature chlorine is only found in the combine star with sodium. In other words it is only found in salt.
The other used in making many everyday products. It is supplies are now usually chlorinated.

5. Other Uses
It is also extensively used in the production of paper products, dyestuffs, textiles, petroleum products, medicines, antiseptics, insecticides, food, solvents, paints, plastics, and many other consumer products

6. More Uses
Most of the chlorine produced is used in the manufacture of chlorinated compounds for sanitation, pulp bleaching, disinfectants, and textile processing. Further use is in the manufacture of chlorates, chloroform, carbon tetrachloride, and in the extraction of bromine

7. Finally Uses
Organic chemistry demands much from chlorine, both as an oxidizing agent and in substitution, since it often brings many desired properties in an organic compound when substituted for hydrogen, as in one form of synthetic rubber

8. Facts Chlorine crystal structure is Orthorhombic
Chlorine’s color is green
Chlorine’s melting point is °F and it’s boiling point is °F

11. Sodium The element’s name is sodium The element’s atomic number is 11
The element’s symbol is Na

12. History
Long recognized in compounds, sodium was first isolated by Davy in 1807 by electrolysis of caustic
It was discovered by Sir Humphrey Davy
It’s name came from soda (Na2CO3)

13. Found in Nature
Sodium is found in nature in fair abundance in the sun and stars. The D lines of sodium are among the most prominent in the solar spectrum. Sodium is the fourth most abundant element on earth, comprising about 2.6% of the earth's crust; it is the most abundant of the alkali group of metals

14. Found in Nature
Also it is now obtained commercially by the electrolysis of absolutely dry fused sodium chloride. This method is much cheaper than that of electrolyzing sodium hydroxide, as was used several years ago

15. Uses
Metallic sodium is vital in the manufacture of esters and in the preparation of organic compounds. The metal may be used to improve the structure of certain alloys, descale metal, and purify molten metals
Also an alloy of sodium with potassium, NaK, is an important heat transfer agent

16. Facts Sodium crystal structure is cube Sodium color is silvery
Sodium melting point is °F and it’s boiling point is °F
