Carbon is one of the most versatile elements in the periodic table. Our bodies are made of carbon. Your bags and water bottles are made up of carbon. The air all around you has carbon. The most metal you see has carbon in it. It is, quite literally, indispensable. Hence, carbon and its compounds are irreplaceable in our surroundings!
Here are some basic facts about carbon:
Atomic Number: 6
Atomic Weight: 12
Allotropes: Atomic Carbon, graphene, graphite, diamond, amorphous carbon (as coal, soot, etc), fullerenes.
Chemical Symbol: C
Number of electrons in the valence shell: 4
CO2 and the Carbon cycle:
CO2, also called carbon dioxide, is an essential constituent of the atmosphere, and a greenhouse gas. One of the most important among carbon and its compounds, it is essential to all life for one major reason: it is consumed by plants, which by the process of photosynthesis, use light as a catalyst to convert CO2 and water to glucose. In the process, they produce oxygen, which is used by nearly every living being that isn’t a plant.
Now, when these plants die, they get buried and can follow one of two paths. They can either act as nutrient sources for the growth of new plants, or they can get compressed over millions of years and form fossil fuels like coal. The carbon from the dead plants can enter the new, living plants, and from there into herbivores and then into carnivores. The animals too die and serve as nutrition for plants, and the cycle begins again. The fuels are consumed in factories and CO2 may be produced.
A major problem has now arisen due to the consumption of fossil fuels (which, obviously, is not a natural process). More CO2 than should exist is being produced, among other gases, and this imbalance leads to the greenhouse effect and global warming, which in turn leads to melting of ice caps and extinction of various species

Answer:
Carbon and its Compounds Notes CBSE Class 10 Science Chapter 4. Bonding in Carbon: The Covalent bond, Electron dot structure, Physical properties of organic compounds, Allotropes of Carbon. ... Thus, carbon overcomes this problem by sharing of its valence electrons with other carbon atoms or with atoms of other elements.
