The popular science article named "Carbon Family" (word 1000) introduces simple carbon and carbon compounds.

Hello, everyone, we come from the carbon family. This is a big family: carbon, carbon monoxide, carbon dioxide, methane, C60, C2H5OH, carbon tetrachloride, C2H4…… ... ...

Let's start with simple carbon. Invite diamonds, graphite, carbon 60 and amorphous carbon to play.

Diamond: I am the most precious person in my family, because I am the hardest substance in nature and the best material for diamonds. I really want to win honor for my family, but most people don't think I belong to the carbon family. That's a real pity.

Graphite: Alas, I am one of the softest minerals in nature. Who told me that my atoms are layered? I was accidentally squashed. But my conductivity is excellent. People use me as graphite electrode and graphite battery. Besides, I think it sounds unfair. The main component of the pencil is my own kind. How can you call it a pencil? You have to change your name.

C60: My atoms are arranged like a football, so my chemical properties are relatively stable. I have been used in the research of materials science and superconductors, but people don't know me well enough. I'm waiting for you to solve the mystery.

Amorphous carbon: everyone contributes to mankind, and of course we are no exception. First of all, we can use it as fuel. Although they can also be used, I think we are the first choice among simple carbon. Let's take a look at the achievements of our members: charcoal and activated carbon can be used to adsorb toxic gases and pigments, and coke can be used to smelt steel. We have made great contributions to mankind.

It is also elemental carbon, but its properties are completely different. It seems that you really can't judge a book by its cover. Next, please welcome representatives of carbon compounds, such as CO, CO2, CH4 and C2H5OH.

CO: hello, everyone. I am a relatively simple carbon-oxygen compound. My relative molecular mass is 28, which is less than the density of air, and I am insoluble in water, so friends with the spirit of "learning from others" can collect my kind in the laboratory, but be careful. Dozens or even hundreds of people are poisoned by me every year, but I can't help it. This is my chemistry. Another chemical property of mine is that it can burn, so it is often used as fuel, but recently I have been gradually replaced by methane. Alas, better than me.

CO2: I am ashamed to face the audience ... I am the chief culprit of global warming, and this crime alone makes me collapse. After global warming reaches a certain level, all icebergs melt, the sea level rises by 7 meters, all coral plants die, and 95% of creatures die ... But I am very wronged, and my volume fraction in the air is only, because human beings blindly develop GDP, waste resources and destroy the environment, resulting in a rapid expansion of my population. Now that global warming has begun, humans have begun to scold me. Alas, if I can't put out the fire, promote photosynthesis and fertilize the gas, human beings will definitely scold me and criticize me every day.

CH4: I am the simplest organic compound. In reality, I am the ideal fuel, but I am still far from hydrogen. When human beings solved the problems of cost, storage and transportation of hydrogen energy, I was eliminated. Actually, I am mentally prepared. Survival of the fittest is a natural law and deeply rooted. Don't be sad, my greenhouse effect is stronger than yours, but my content in the air is much less than yours, otherwise it will be terrible.

C2H5OH: You know what? I am the main ingredient of mellow and good wine. I can make people intoxicated with the aroma of wine, make people energetic, and also make people mentally anesthetized, thus making abnormal and irrational behaviors. Look at the trouble caused by those drunk drivers. It's all my fault. I can also be a fuel, and the fuel used in the laboratory is basically me. In order to save fossil fuels, people often add a certain amount of me to gasoline. I can also disinfect the wound to prevent inflammation, but the concentration is very high, only 70-80%.

After listening to the self-reports of the main members of the carbon family, I believe you have a deeper understanding of the carbon family. Although people talk about "low-carbon life" all day, the carbon family actually plays an important role in people's lives.
