What is the difference between atomic mass and atomic number? Atomic mass is the average weighted mass number of all isotopes of a given element. It is calculated based on the frequency of different isotopes of that element. Atomic number is the number of protons in an atom's nucleus. It ...
Atomic Number • Hydrogen has one proton in the nucleus, and 1 electron around its nucleus. • Oxygen has eight protons in the nucleus, and eight electrons around its nucleus. Mass Number • Mass number is made up of the total number of ...
and the atomic mass are either very close or else the same. In introductory chemistry, it's probably fine to consider them to mean the same thing. However, there are two cases in which the sum of the protons and neutrons (atomic mass number) is not quite the same as the atomic mass!
atomic mass 原子质量 mass number 质量数 前者是多少克，后者是多少个 提示一下你就应该明白了，喝喝
Atomic Number for any two different atoms is never same and hence can be used to distinguish two different atoms. Mass Number It is the sum of neutrons and protons of an atom present in nucleus. Mass Number for two different atoms can be same. The Atomic Mass of an atom is approximately...
