  1. Carbon By: Hana Taha Grade 8 Science

  2. Carbon Atomic number: shows the number of electrons and protons Carbon 6 C 12.011 Element/chemical symbol: represents the name Atomic mass: shows the sum of neutrons + protons Protons: 6 Electrons: 6 Neutrons: 6 To get the number of neutrons in an element, you have to subtract the atomic number from the atomic mass. The difference would be the number of neutrons in the element.

  3. Carbon • CO2- Carbon Dioxide- The most familiar example for the use of carbon dioxide is its use in soda or beer which makes the drinks fizzy and appealing to the consumer. • Carbon + Oxygen = Carbon Dioxide • C + 2O = CO2 • CuCO3- Copper Carbonate- Copper carbonate is sometimes used for the color it produces in fireworks. Small amounts of copper carbonate are sometimes used in animal feeds and fertilizers. • Copper + Carbon + Oxygen = Copper Carbonate • Cu + C + 3O = CuCO3 • (NH4)2CO3- Ammonium Carbonate- It is used in baking powders, mortal dyeing and tanning. As medication, it is used in reagents and smelling • Nitrogen + Hydrogen + Carbon + Oxygen = Ammonium Carbonate • 2(N + 4H) + C + 3O = (NH4)2CO3

  4. Carbon • CaCO3- Calcium Carbonate- Calcium carbonate has been used to make chalks that have been used to write on black boards back in the days. Calcium carbonate is one of the main minerals used in paper, plastic, paint and coating industries. It works as both a filter and a coating pigment. • Calcium + Carbon + Oxygen = Calcium Carbonate • Ca + C + 3O = CaCO3 • NaCO3- Sodium Carbonate- When combined with sand and calcium carbonate, sodium carbonate can be heated and then cooled to make glass. Sodium carbonate is also used in many laundry detergents as it is one of the main ingredients. • Sodium + Carbon + Oxygen = Sodium Carbonate • Na + C + 3O = NaCO3

  5. Carbon • In order for plants to keep living and keeping our environment and world in balance, carbon needs to exist. • It is one of the main components of carbon dioxide and without carbon dioxide plant life would die, which would soon lead to animal death and human extinction. • Without plant life, humans couldn’t get their daily amount of carbohydrates which are found in crops like wheat and flour. • Carbon is also the most important ingredient in fossil fuels. • Carbon can also help scientists get a good idea of the age of an organic item or material such as a fossil or a piece of wood. Why It Is Important And Its Uses Today

  6. Carbon • Carbon was mixed with sulphur and saltpeter to make gunpowder used to fire cannons and muskets of the 1900's and before. • Carbon was used to clean water in remote villages in the past times. • Carbon was mixed with clay and used to make pencil leads.Carbon can be burnt with limited air supply to make carbon monoxide. Carbon monoxide gas was used to kill poultry and animals in humane ways before slaughter . • Melting Point: 3500.0 °C (3773.15 K, 6332.0 °F) Boiling Point: 4827.0 °C (5100.15 K, 8720.6 °F) • Martin D. Kamen discovered the element carbon. • The four main allotropes of carbon are graphite, diamond, amorphous carbon and fullerenes but the most common ones are graphite and diamond. • Carbon is a non-metal. • Carbon prices vary and change depending on the amount and the time. Right now the cost for pure carbon is $2.4 per 100g. Uses In The Past And Other Facts

  7. Carbon • Carbon can be found in substances of all 3 different states of matter. • Carbon can be found in diamond and graphite which are solid. • Diamond, beingthe hardest naturally occurring substance known to man, is commonly used in jewelry mainly for its beauty and durability. Diamond can be used in earrings, necklaces, rings, pendants and so much more. It can even be used to decorate structures or clothes. • Graphite is used in pencils and in writing utensils. • Carbon (in the form of coal, which is mainly carbon) is used as a fuel. Solids

  8. Carbon • Carbon is found in crude oil (petroleum) and in gasoline which is used to run cars, trains, airplanes and other machinery. (liquid) • Carbon is also found in fossil fuels and methane gas. It is also a main ingredient of carbon dioxide which is used in fire extinguishers as an alternative for water. It is also used in medical gases and in carbonated drinks such as soda and beer. Liquids and Gases

  9. Carbon • Carbon can be obtained by burning organic compounds with insufficient oxygen. • Natural diamonds are found in kimberlite from ancient volcanoes. • Graphite can be found in natural deposits. • Carbon is found everywhere on this planet. It can be found in the air, in animals and plants and even in the human body. • Carbon is not only found on planet Earth but also in the Sun, atmosphere, stars and comets. • Graphite is a common form of carbon, it is found in countries such as Sri Lanka, U.S.A., and Germany. • Diamonds are found in Igneous rocks and come mainly from South Africa. Location

  10. Carbon • It's the sixth most common element in the universe and the 15th most common one in the Earth's crust. • Car tires are black because they are about 30% carbon black, which is added to rubber to strengthen it. The carbon black also helps protect against UV damage to the tires. • About 20% of the weight of living organisms is carbon. • The carbon atoms in your body were all once part of the carbon dioxide fraction of the atmosphere. • Carbon undergoes nuclear fusion reactions in heavy stars to make neon, magnesium and oxygen.
