Thenumber of atomscontained in the relative atomic mass of an element has been shown byAvagardro to be 6.02×1023. This number is called theAvagadro numberor theAvagadro constant. An alternative definition for the relative atomic mass of an element is the mass of 6.02 × 1023atoms of the...
Atomic Mass- Atomic mass is the mass of an atom or other particle, expressed in unified atomic mass units (u). An atomic mass unit is defined as 1/12th the mass of a carbon-12 atom. Since the mass of electrons is much smaller than that of protons and neutrons, the atomic mass is ...
The masses of stable Si atoms, of possible importance for the definition of the kg, the only base unit not yet defined in terms of natural constants, are given with 80 ppb (200 eV) accuracy. A repeated Penning trap result for Si with a 100 ppb precision confirms the mass table result....
