atomic mass跟atomic number的詳細介紹 考試用 答案 atomic mass:原子质量 atomic number:原子数 原子质量是指此原子核中中子和质子的总质量(一般是指相对质量,就是Al质量=27之类的).原子数是指此原子中质子的数量,决定此原子属于什么元素.相关推荐 1atomic mass跟atomic number的詳細介紹 考試用 反馈 收藏 ...
The meaning of ATOMIC NUMBER is an experimentally determined number characteristic of a chemical element that represents the number of protons in the nucleus which in a neutral atom equals the number of electrons outside the nucleus and that determines t
What is Atomic Number & Mass Number - The atomic number or proton number (symbol Z) of a chemical element is the number of protons found in the nucleus of every atom of that element. Visit BYJU'S to learn more about atomic numbers.

原子质量数(mass number),以A表示,等于原子核中的质子数(Z)加上中子数(N)。由于质子和中子的质量非常接近原子质量单位,因此原子的质量数可以近似地看作是该原子的质量(以AMU为单位)。例如,氢-1(^1H)的原子质量数为1,其原子质量也接近1 AMU。 4. 与相对原子质量的区别:原子质量与...
