1. Introduction

In this age of environmental consciousness, the term cảbon has taken center stage. But what exactly is it, and why is it essential for us to pay attention to it? Let’s begin our journey into the world of carbon.

2. What is Cảbon?

Cảbon, also known as carbon in English, is a chemical element with the symbol “C” and the atomic number 6. It is one of the fundamental building blocks of life and is found in various forms in both organic and inorganic compounds.

Carbon is notable for its versatility and its ability to form a wide range of compounds due to its unique bonding properties. It is a key component of all known life forms, making up a significant portion of organic molecules such as proteins, carbohydrates, fats, and DNA. In the form of carbon dioxide (CO2), it is also a crucial component of Earth’s atmosphere.

The carbon cycle plays a fundamental role in the planet’s ecosystems. Plants and algae absorb carbon dioxide from the atmosphere during photosynthesis, converting it into organic compounds and releasing oxygen as a byproduct. This process is essential for sustaining life on Earth.

Beyond its role in biology, carbon has many industrial applications, including in the production of fuels, plastics, and various chemicals. However, the excessive release of carbon dioxide into the atmosphere, primarily from the burning of fossil fuels, has led to concerns about climate change and global warming due to the greenhouse effect.
