Atomic mass - Wikipedia, the free encyclopedia
The atomic mass of a chemical element is the mass of an atom at rest, most often expressed in unified atomic mass units . The atomic mass is often synonymous with relative atomic mass , average atomic
Atomic Mass Units
Atomic Mass Units Do we now know how much atoms really weigh, in pounds or grams? Yes, but we don't normally use those units for measuring the mass of an atom
Theory of atomic-mass calculation
How can I calculate a significant atom-mass from the Atomic Number Order ?     Z=(input): EGT = -2: ATM = 0 For H = 1 To 16         EGT = EGT + FNA(H)
