原子质量单位

Atomic mass unit

统一的原子质量单位或达尔顿是用于指示原子或分子量表的质量的标准单位。 一个统一的原子质量单位近似为一个核子的质量,等于1g / mol。 定义为核 - 电子基态碳-12的未结合中性原子质量的十二分之一,值为1.660538921×10-27公斤。 CIPM将其分类为接受SI使用的非SI单位,其SI值的值必须通过实验获得。 没有“统一”前缀的amu在技术上是一个基于氧气的过时单位,在1961年被替换。然而,一些来源仍然使用amu,但现在以与u相同的方式定义它。 在这个意义上说,大多数原子质量单位或者今天的使用实际上是指统一的原子质量单位或者u。 为了标准化,必须选择特定的原子核,因为核子的平均质量取决于原子核中由于质量缺陷而产生的核子的计数。 这也是为什么质子本身大于1 u的原因。 The unified atomic mass unit or dalton is the standard unit that is used for indicating mass on an atomic or molecular scale. One unified atomic mass unit is approximately the mass of one nucleon and is equivalent to 1 g/mol. It is defined as one twelfth of the mass of an unbound neutral atom of carbon-12 in its nuclear and electronic ground state, and has a value of 1.660538921×10−27 kg. The CIPM has categorised it as a non-SI unit accepted for use with the SI, and whose value in SI units must be obtained experimentally. The amu without the "unified" prefix is technically an obsolete unit based on oxygen, which was replaced in 1961. However, some sources still use the amu but now define it in the same way as u. In this sense, most uses of atomic mass units or amu today actually refer to unified atomic mass units or u. For standardization a specific atomic nucleus had to be chosen because average mass of a nucleon depends on the count of the nucleons in the atomic nucleus due to mass defect. This is also why the mass of a proton by itself is more than 1 u.
