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...

Proton number 原子的质子数(原子数)为原子核内所含的质子的数量。这也是元素周期表的排布顺序。 Isotope 同位素是质子数相同但是中子数不同的相同元素。 Mass number 一个原子的质量数是其中子和质子数量的总和。 原子的完整符号以其质量数为...
Proton number 原子的质子数(原子数)为原子核内所含的质子的数量。这也是元素周期表的排布顺序。 Isotope 同位素是质子数相同但是中子数不同的相同元素。 Mass number 一个原子的质量数是其中子和质子数量的总和。 原子的完整符号以其质量数为上角标,原子数为下角标。
in any atom, the number of electrons equals the number of protons. indentifying elements atoms may be identified by their atomic number and mass number. the notation He means that helium has an atomic number of 2 and a mass number of 4. isotopes of an element differ in the number of ...
What are the atomic number and the mass number of this isotope? Answer Atomic number = 50, mass number = 118 When referring to an atom, we simply use the element’s name: the term sodium refers to the element as well as an atom of sodium. But it can be unwieldy to use the name ...
