Carbon  

 

 

  Carbon is represented by the element symbol  C  and atomic number 6. Carbon comes from the Latin word carbo, which means coal.  It is a nonmetallic tetravalent - making four electrons availible to form covalent chemical bonds. All life depends on carbon.It is in almost every biological compound that makes up our bodies, systems, organs, cells, and organelles. When we breath in we breath out carbon dioxide ( CO² ).   Carbon has been used for thousands of years, but was never really discovered.

 

                                                                         

 

The Different Forms of Carbon

 

1. Dry Ice:  Dry ice is the solid form of carbon. It's frozen carbon dioxide with a temperature of -78.5°C and melts into a gas rather than a liquid form to creat the popular smoke effect.

 

2. Fizzy Drinks:   when held under pressure carbon dioxide dissolves into water, and it then causes bubbles on your tongue as it forms a carbonic acid as you take a gulp.

 

3.Carbon Dating:  The age of fossils and minerals can be found by using carbon - 14 which is a radioactive isotope of carbon.

 

4.Teeth Whitening:  Carbon is the key element in teeth whitening treatments, found as carbon admide peroxide in both dentist and over-thecounter treatments.

 

5. Fire Extinguishers:   A fire extinguisher containing carbon dioxide is mainly used for fighting electrical fires. The carbon goes back into the atmosphere without leaving any harmful fumes.

 

6. Pencils:  Graphite is used in pencils for writing, and is a form of carbon.

 

7. Diamonds:   A diamond is a different form of carbon. The carbon atoms in a diamond are arranged in a strong, tetrahedral structure. The word diamond comes from the Greek word meaning unbreakable.

 

8. Plants:   Carbon is the most important element in plants. Without it plants would not exist.

 

9. Charcoal:    The main ingredient in charcoal is carbon.

 

10. Petrolium Products:  Carbon is the most important element in gaseoline. Since gaseoline is made up of oil and oil is made from dead plants it has carbon in it.

 

The Carbon Cycle   

       

         The ocean, air, rocks and all living things are made of carbon. Since Earth is a dynamic place carbon does not stay still. It's always on the move. In the atmosphere, carbon is attached to some oxygen in a gas called carbon dioxide. The plants use that carbon dioxide and sunlight to make thier own food and grow. That carbon becomes a part of the plant. Plants that die and burried may turn into fossil fuels made of carbon like coal and oil over millions of years. Then when humans burn fossil fuels it quickly returns to the atmosphere as carbon dioxide.Carbon dioxide is a greenhouse gas and traps heat in the atmosphere. Without it and other greenhouse gases, the Earth would be a frozen landscape. But since humans have been burning more and more fossil fuels, there is 30% more in the atmosphere than there was 150 years ago, and Earth is becoming much warmer.

 

Atomic Number

 

  • The atomic number of an element is the number of protons in an atom.
  • The number of protons in the nucleus make an atom different from each other.
  • The number of protons in an element never changes.
