Urgent! ! Report on Chemistry Learning in Micro-world

Wang Yiying, Class 93, No.6 Middle School, Yichang City, Hubei Province

Before there were intellectuals and atoms, the world in our eyes was like this: clear mountains and green waters, blue sky and white clouds, rows of high-rise buildings and endless traffic, which formed a colorful world. After I learned the knowledge about the composition of matter, I had a new understanding of what constitutes matter. A brand-new microcosmic world was presented to me, and everything was new, which greatly stimulated my interest in learning. For example, I swam in the microcosmic world in a boat, and learned that molecular atoms can form substances, and atoms can be divided into nucleus and extranuclear electrons. This wonderful world is like a huge magnet at any time and place, attracting me and leading me forward, so I have some thoughts and discoveries.

I was deeply impressed by the study of the topic of ions, and the passages in the book kept fresh in my memory.

the movement of electrons outside the nucleus has its own characteristics, and they have their own running regions, which are called electron layers. Extranuclear electrons move in different electron layers, which is called layered arrangement of extranuclear electrons. We know that rare gas elements, such as argon and neon, have eight outermost electrons (helium has two). Because they are chemically inert and inert, people think that the outermost layer has a structure of eight electrons (only one electron layer has two electrons), which belongs to a stable structure. Generally, there are more than four outermost electrons in nonmetallic elements, so it is easy to get electrons in chemical changes and achieve a relatively stable structure.

I have deep feelings about this passage. When metal elements react with other elements, they even "sacrifice" their own electrons and give them to each other, making both sides smile. In chemical changes, the selfless dedication of metal elements is worth learning. Isn't it the same for us to be human? We observe everything around us with keen eyes, treat people around us with a fiery and sincere heart, think more about others, care for others, and sacrifice ourselves to make others happy. I think the joy we get from helping others is almost the same as the "happiness" when metals are combined. Fan Zhongyan said: "The worries of the world are the best first, and the joy of the world is the last." It also tells us to contribute to others, and the devotee gains a happiness, a lofty emotion, the respect and love of the agent, and the continuation of his own life. The spirit of metal elements losing electrons is worth promoting. What about nonmetallic elements? I think they are just like those arrogant little people who are self-centered in life. They always ask others to serve them, but they never think about how much they have paid for others. Although without them, compounds can't be formed, but this kind of behavior should be abandoned by society. Dedication and taking are a pair of contradictions. People who are bent on taking are never satisfied with their greed. Moreover, without the dedication of others, what can they ask for? Therefore, we need people with dedication like metal elements.

The revision of chemistry textbooks is a revolution in chemistry learning. I think it is a realm to learn some philosophy of life from learning chemistry after mastering the book knowledge. I think this is a realm that comes from learning and is higher than learning. The microcosmic world is like the ocean, vast expanse. I will keep discovering and feeling with this curiosity.
