Carbon

Carbon is a chemical element with the symbol C and atomic number 6. It is a non-metal with a variety of forms, including graphite, diamond, and amorphous carbon. It is the fourth most abundant element in the universe and is a key component of all known life on Earth.

Atomic Structure

The carbon atom consists of six protons and six neutrons in its nucleus, with six electrons orbiting the nucleus in two energy levels. The electron configuration of carbon is 1s² 2s² 2p².

Physical Properties

• Appearance: Carbon exists in various forms, including black, opaque graphite and clear, transparent diamond.
• State: It can exist in solid, liquid, and gaseous states depending on the form.
• Melting Point: The melting point of carbon varies depending on the form, with graphite melting at around 3,550°C and diamond melting at around 3,825°C.
• Boiling Point: Carbon sublimes at around 3,825°C, transitioning directly from a solid to a gas without passing through the liquid phase.

Chemical Properties

• Reactivity: Carbon is relatively unreactive at room temperature, but it can form compounds with a wide range of elements, including hydrogen, oxygen, nitrogen, and many others.
• Bonding: It forms covalent bonds with other elements, resulting in a variety of organic and inorganic compounds.
• Allotropes: Carbon has several allotropes, including graphite, diamond, and fullerenes, each with unique properties and structures.

Uses

Carbon has numerous industrial, commercial, and biological applications, including as a key component in steel production, as a fuel source in the form of coal and petroleum, in the production of plastics and polymers, and as a fundamental element in all living organisms.
