解析 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.结果一 题目 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...
Are Atomic Mass and Atomic Mass Number the Same? Yes and no. If you are talking about a sample of a single isotope of an element, the atomic mass number and the atomic mass are either very close or else the same. In introductory chemistry, it's probably fine to consider them to mean...

Understand the definition of atomic mass, atomic number, and atomic weight. Discover how to find atomic mass, and learn what an atomic number represents. Updated: 11/21/2023 Table of Contents What is an Atomic Number? Atomic Mass Atomic Weight: Atomic Mass and Isotopes Lesson Summary ...
Mass number is not shown on the periodic table but is often found when elements are shown as symbol-mass number (such as oxygen-16). 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 ...
The mass number reports the mass of the atom’s nucleus in atomic mass units (amu). Isotopes are atoms with the same atomic number but different neutron numbers and thus different mass numbers. A little more than three-quarters of naturally occurring elements exist as a mixture of isotopes, ...
