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.
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...
Atomic Number, Mass Number, Atomic Mass and Isotopes Mrs. Coyle Chemistry Atomic Number (Z): is the number of protons in the nucleus of the atom. Z=#p • The number of protons (atomic number) determine the identity of an element. Atoms have no overall electrical charge so, an atom ...

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 the same thing. However, there are two cases in...
