英语翻译
Mendeleev arranged the known elements in order of increasing atomic weight (molar mass)
请问这句话后面的increasing atomic

英语翻译Mendeleev arranged the known elements in order of increasing atomic weight (molar mass)请问这句话后面的increasing atomic
在物理中,mass = 质量;weight = 重力.两个概念是严格区分的.
在化学中,atomic weight = atomic mass = 原子量,mass与weight是不分的.
原子量 = number of protons and neutrons = 原子内的质子数与中子数之和
= number of nucleons = 原子内的核子数.
increasing atomic weight = 按照递增规律排列的原子量.
Mendeleev arranged the known elements in order of increasing atomic weight (molar mass)
= 门捷列夫按照(当时)已知的元素按照原子量递增的规律排列起来(摩尔质量)

升序的原子质量
