Chemical Periodicity and the Periodic Table 2.3.1 Trends in atomic and physical properties Figure 2.1 shows a modern version of Lothar Meyer's atomic volume curve: the alkali metals appear at the peaks and elements near the centre of each period (B, C; Al, Si; Mn, Fe, Co; Ru; and Os...
The atomic mass unit is defined in terms of the stable carbon nuclide 12C, which is assigned an atomic mass of exactly 12.000000 u. Thus the atomic mass unit is by definition exactly 1/12 the rest mass of 12C, or [2.5]1u=1.66053873×10−27kg. The masses of all the nuclides in atom...
