Version 6.1
September 2010 |
A PDF version of the Periodic Table without crop marks is now available.
|
Version 6
September 2010 |
The online version of the Periodic Table has been updated to the most recent printed version, which is dated September 2010. There was also a September 2009 version. Since version 4, elements have been added such that there are no "missing elements" from 1 to 118. Several official names have been added for high Z elements.
|
Version 4
November 2005 |
A home page and version history for the periodic table were designed and a high-resolution TIFF file was made available; fifth & sixth printings of NIST SP 966 occurred in September 2004 & September 2005 with no changes to the data values. |
Version 4
September 2003 |
The ionization energy value was updated for Po; fourth printing of NIST SP 966. |
Version 3
September 2002 |
The ionization energy values were updated for Ne, Pu, and Cm; the atomic weight values were updated for Zn, Kr, and Dy; and the element with atomic number 118 was removed from the periodic table after a retraction by the Lawrence Berkeley National Laboratory; third printing of NIST SP 966. |
Version 2
March 2001 |
The ionization energy values were updated for Y, Sm, Gd, Pt, and Bi; elements with atomic number 114, 116 & 118 were added to the periodic table; second printing of NIST SP 966. |
Version 1
April 1999 |
Periodic Table: Atomic Properties of the Elements available online as a PDF file. All data contained in the periodic table are available from the following three databases:
- Ground Levels and Ionization Energies for the Neutral Atoms
- Atomic Weights and Isotopic Compositions
- Fundamental Physical Constants
