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...
It is the number with a decimal on the periodic table and is often listed below the symbol for the atom. 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...

元素周期表(Periodic Table)分为周期(Period)与族(Group),可帮助预测元素的性质和反应。 原子序数(Atomic Number)等于质子数,相对原子质量(Relative Atomic Mass)是各同位素的平均质量。 通过本节的学习,你已经了解原子的基本结构、元素周期表的用法以及如何计算相对原子质量,接下来可进入下一节:化学键与分子结构的学...
