What is Atomic Number and Mass Number? Atomic number and mass number are always whole numbers because they are obtained by counting whole objects (protons, neutrons, and electrons). The sum of the mass number and the atomic number for an atom (A-Z) corresponds to the total number of ...

75.53 of these atoms each have a mass of 35 atomic mass units (AMU), and 24.47 atoms each have a mass of 37 AMU. The word mole has been adopted to represent the Avagadro number of atoms of an element, that is, the relative atomic mass of an element. Thus, one mole of sodium ...
Atomic number (Z) Integer equal to the number of protons in a nucleus; the order of an element in the periodic table. Atomic weight or nuclear mass number (A) An integer equal to the sum of the number of protons Z and neutrons N. Isobar Member of a set of nuclides of the same at...
Learn about Stoichiometry and Stoichiometric Calculations here. What is Atomic Mass? Atomic mass of an element is the number of times an atom of that element is heavier than an atom of carbon taken as 12. One atomic mass unit is equal to one-twelfth of the mass of an atom of carbon 12...
