CARBON AND ITS COMPOUNDS Covalent Bond: A chemical bond formed by the sharing of two atoms. Types of Covalent Bonds i. Single Covalent Bond: A type of bond formed by sharing of one pair of electrons between two atoms. ii. Double Covalent Bond: A type of bond formed by sharing of two pairs of electrons between two atoms. iii. Triple Covalent Bond: A type of bond formed by sharing of three pairs of electrons between two atoms. Properties of Covalent Bond i. Their B.P. and M.P

Carbon fibre-reinforced carbon (aka carbon–carbon‚ abbreviated C/C) is a composite material consisting of carbon fibre reinforcement in a matrix of graphite. It was developed for the nose cones of intercontinental ballistic missiles‚ and is most widely known as the material for the nose cone and wing leading edges of the Space Shuttle orbiter. It has been used in the brake systems of Formula One racing cars since 1976; carbon–carbon brake discs and pads are a standard component of Formula One brake

Carbon and Its Compounds Carbon: Introduction Atomic Number: 6 Electronic Configuration: 2‚ 4. Valence electrons: 4 Property: Non-metal Abundance:- Carbon is the 4th most abundant substance in universe and 15th most abundant substance in the earth’s crust. Compounds having carbon atoms among the components are known as carbon compounds. Previously‚ carbon compounds could only be obtained from a living source; hence they are also known as organic compounds. Bonding In Carbon:- The Covalent

important‚ this being carbon. There are many interesting things about carbon including‚ facts about it‚ its history‚ and what it is used for. Carbon is a very important element‚ in fact‚ life could not exist without it. Carbon (C on the periodic table) is a chemical element and is the sixth most abundant element in the world. Carbon is the 6th element on the periodic table in group 14‚ period 6‚ it has six protons‚ six electrons‚ and six neutrons‚ with an atomic mass of 12.01u. Carbon has a boiling point

The Carbon Cycle The element Carbon is the principle block for the organic compounds that make up life. This is because the study of the Carbon Cycle draws upon theories from biology‚ chemistry‚ geology and oceanography in order to understand the movement of carbon throughout the atmosphere‚ hydrosphere‚ and geosphere. Carbon is made up of four electrons that are able to form with each other; this causes the many different forms of carbon. The most popular form of carbon is carbon dioxide; this

Carbon Cycle Living organisms are significant in the recycling of numerous elements contained in an ecosystem. One of the elements is carbon. Carbon is nonmetal‚ forms over ten million different compounds‚ found in minerals‚ oceans‚ and is the main component of biological compounds. So how do living organisms and their biochemical reactions contribute to the recycling of carbon? Carbon moves through the ecosystem in a cycle‚ in which the living organisms take and release

destructive nature. I will start by describing the carbon cycle and how elements of my lifestyle impact the cycle. Photosynthesis converts the Carbon dioxide gas that exists in the atmosphere and in dissolved water to organic carbon. Organic carbon is brought back into carbon dioxide gas by a process called respiration. There are sources of organic carbon underground in the form of fossil fuels‚ human emissions and volcanic activity brings the stored carbon back into the cycle. As a human being who feed

Unsaturated organic compounds : Organic compounds in which a double or a triple bond exists between two carbon atoms in a carbon chain‚ are called unsaturated organic compounds. 10. Hydrocarbons : Organic compounds which contain only carbon and hydrogen atoms are called hydrocarbons. 11. Straight chain hydrocarbons : Hydrocarbons‚ in which all the carbon atoms are linked to one another in a straight chain

one form. Carbon is one of the elements that contain many allotropes. Each allotrope of carbon has its own different properties. The allotropes of carbon are diamond‚ graphite‚ fullerenes‚ carbon nanotubes‚ carbon nanobuds‚ amorphous carbon‚ glassy carbon‚ lonsdaleite‚ and carbon nanofoam. Diamond is the best know allotrope of carbon. It is the hardest known natural mineral which makes it very rough. In the structure of the diamond‚ each carbon atom is covalently bonded to four other carbon atoms and

The carbon cycle shows how carbon is recycled -Carbon dioxide is taken in by plants in order to carry out photosynthesis and make food. -The carbon from the carbon dioxide is used to make carbohydrates‚ fats and proteins that make up the plant body. For example the cell wall of plants is made from cellulose - a carbohydrate. -Some of this carbon is returned into the atmosphere as carbon dioxide when the plant respires. When these plants are eaten by other animals this carbon becomes part
