covalent的音標為[k??"v?l?nt],基本翻譯為“共價鍵的;共價結合的”。
速記技巧:可以將單詞拆分為“co-”和“valent”兩個部分,“co-”意為“共同”,“valent”意為“有吸引力的”,整體含義為“共同有吸引力的”,即“共價鍵的;共價結合的”。
Covalent這個詞來源于拉丁語,意思是“共價的”。它的變化形式包括名詞covalence和形容詞covalent。
相關單詞:
1. Covalence(共價):這是一個名詞,指兩個或多個原子通過共享電子對形成的鍵。
2. Covalently bound(共價鍵):這是一個形容詞短語,用于描述由共價鍵連接的分子或原子。
3. Covalent bonding(共價鍵結):這是一個名詞短語,指通過共價鍵形成的化學鍵結。
4. Covalent bonding electron pair(共價鍵電子對):這是一個名詞短語,指通過共享電子對形成的化學鍵。
5. Covalent bond(共價鍵):這是一個動詞短語,用于描述兩個原子通過共享電子對形成的化學鍵。
6. Covalent bond strength(共價鍵強度):這是一個名詞短語,指共價鍵的強度。
7. Covalent bonding energy(共價鍵能):這是一個名詞短語,指形成共價鍵所需的能量。
8. Covalent compound(共價化合物):這是一個名詞短語,指由共價鍵形成的化合物。
9. Covalent bond energy(共價鍵能):這是一個形容詞短語,用于描述共價鍵的能量。
10. Covalent bond dissociation(共價鍵解離):這是一個動詞短語,指共價鍵的斷裂或分解。
以上這些單詞都與化學中的共價鍵有關,是化學和物理學中的重要概念。它們在科學和工程領域中有著廣泛的應用。

英文小作文:
Covalent bonds are essential for the stability and function of chemical compounds, which are crucial for life on Earth. From DNA to polymers, covalent bonds play a vital role in the chemical processes that occur within our bodies and the environment around us. Understanding covalent bonding is fundamental to understanding the world around us, and it is essential for chemists, biologists, and other scientists who work in the field of chemistry and biology. However, covalent bonds are not just important for science; they also have practical applications in technology and industry, such as in the production of polymers and other materials that are used in daily life. Therefore, covalent bonds are not only fundamental to understanding the world around us, but they also have practical applications in our daily lives.
