... 21. The periodic table of the elements does not list whole numbers for atomic weights. Why? A. The atomic weights are not predictable. B. The atomic weights include protons and neutrons at 1 amu each, but they also include electrons, which weigh a lot less than one. C. The atomic weight is the weigh ...

... The mass number of an element, A, is the number of nucleons (protons and neutrons) in the atomic nucleus. Different isotopes of a given element are distinguished by their mass numbers, which are conventionally written as a super-index on the left hand side of the atomic symbol (e.g., 238U). The rela ...
