atomic weight的音標(biāo)為[??t?mik we?θ]，基本翻譯為“原子量”，速記技巧為“阿鐵米克韋次”。

Atomic weight（原子量）這個(gè)詞的英文詞源可以追溯到古希臘語(yǔ)中的“atomos”（原子）和“weight”（重量）。原子量是用來(lái)衡量一個(gè)原子的質(zhì)量的一個(gè)數(shù)值。

變化形式：通常以字母“A”表示，在某些文獻(xiàn)中，也使用“atomic weight number”來(lái)表示。

相關(guān)單詞：

1. molecular weight（分子量）：這個(gè)詞是由“molecule”（分子）和“atomic weight”（原子量）組成的，用來(lái)表示分子的質(zhì)量。

2. isotope（同位素）：這個(gè)詞是由“isotope”（相同原子序數(shù)的不同元素）組成的，用來(lái)描述具有相同原子序數(shù)但質(zhì)量不同的原子。

3. atomic number（原子序數(shù)）：這個(gè)詞是由“atomic”（原子的）和“number”（數(shù)字）組成的，用來(lái)表示元素在周期表中的位置，即該元素原子中質(zhì)子數(shù)。

這些單詞在化學(xué)和物理學(xué)中非常重要，它們反映了原子量和原子結(jié)構(gòu)等基本概念在科學(xué)研究中扮演的重要角色。這些概念的發(fā)展推動(dòng)了科學(xué)技術(shù)的進(jìn)步，對(duì)人類(lèi)社會(huì)產(chǎn)生了深遠(yuǎn)的影響。

The Atomic Weight of Matter: An Introduction

The atomic weight of matter plays a crucial role in chemistry and physics. It refers to the mass of an atom, which determines its chemical properties and reactivity. Understanding the atomic weight of various elements is essential for understanding the structure and function of molecules and compounds.

Hydrogen, oxygen, carbon, nitrogen, sulfur, phosphorus, and chlorine are some of the common elements that have been studied extensively for their atomic weights. These elements are essential for life and are found in various forms in our environment and in various products we use every day. Understanding their atomic weights helps us better understand the properties and functions of these elements and their compounds.

For instance, hydrogen has an atomic weight of 1.09 amu, making it the lightest element on the periodic table. This property makes it useful in various industrial processes and in hydrogen fuel cells, which are becoming increasingly popular for their clean energy production. On the other hand, chlorine has an atomic weight of 35.5, making it a crucial element in the production of many chemicals and pharmaceuticals.

In conclusion, the atomic weight of matter is an essential concept in chemistry and physics that helps us understand the structure and function of various elements and their compounds. Understanding the atomic weights of common elements such as hydrogen, oxygen, carbon, nitrogen, sulfur, and chlorine is crucial for understanding our world and for developing new technologies and products that are beneficial for our lives.
