Details
The values for Element.mass
were taken from the abridged standard atomic weights (Table 2), with the following exceptions:
- When a range of atomic weights was presented, the value was taken from Table 3 (conventional atomic weights).
- When an abridged standard atomic weight was not provided, the value was taken as the mass number of the longest-lived isotopes (Table 4).
These choices follow the convention used for the NIST periodic table.
Atomic radius
We provide two options for the van der Waals radius, the Bondi radii, and the Alvarez radii.
Bondi radii
The values were taken from Tables I and XIV of 1964 paper by Bondi. Values for Hg, Cd, and Zn came from Table I of the 1966 paper.
