IUPAC Standard atomic weights of the elements
Description
A data set containing the standard atomic weights of the elements as recommended by the International Union of Pure and Applied Chemistry (IUPAC) and Commission on Isotopic Abundances and Atomic Weights (CIAAW).
Usage
IUPAC_StdAW
Format
A data frame with 118 rows and the following
8 columns:
- Element
Element's name
- Symbol
Element's symbol
- Atomic number
Element's atomic number. Elements are listed in increasing atomic number
- stdAW::Value
Values of standard atomic weights are given as single values with uncertainties (column stdAW::Uncertainty) or as intervals.
- stdAW::Uncertainty
of the Value of the standard atomic weight
- abrStdAW::Value
Abridged atomic weights quoted to five significant figures. Unless such precision cannot be attained due to the variability of isotopic composition in normal materials or due to the limitations of the measurement capability.
- abrStdAW::±
A plus-minus-value as a simplified measure of the reliability of the abridged values.
- Note
The collected footnotes of the table. Notes are resolved to the sentences associated with them. If there is more than one note, the notes are separated by an newline (
\n).
Details
This is table 1 of (Prohaska et al. 2022). The (foot)notes in the table have been collected in a new column (Notes) and their abbreviations resolved into sentences.
