The INTERNET Database of Periodic Tables
There are thousands of periodic tables in web space, but this is the only comprehensive database of periodic tables & periodic system formulations. If you know of an interesting periodic table that is missing, please contact the database curator: Mark R. Leach Ph.D. The database holds information on periodic tables, the discovery of the elements, the elucidation of atomic weights and the discovery of atomic structure (and much, much more).
Periodic Tables from the year 1998 :
| Year: 1998 | PT id = 116, Type = misc data |
Gray's Wooden Periodic Table Table
Theodore Gray's Wooden Periodic Table Table a wooden table that incorporates a periodic table is a treasure trove, both on the web and in reality (his office).
The web site contains over 12 gig of data and beautiful images. Explore!
Theo's new site is periodictable.com.
| Year: 1998 | PT id = 120, Type = data |
American Elements
Supplier & Element Industrial Information: American Elements
| Year: 1998 | PT id = 178, Type = non-chem |
Perl Operators
A periodic table of Pearl Operators: "Being a comprehensive and complete enumeration of the Operatic Elements of the Perl 6 Language, assembled and drawn with dedication and diligence by M. Lentczner as a service to both the Community and the Republic."
| Year: 1998 | PT id = 190, Type = non-chem |
Silicon Graphics Workstation/Client
Silicon Graphics Workstation/Client periodic table:
| Year: 1998 | PT id = 245, Type = data |
NMR Nuclear Spin Periodic Table(s)
An nuclear magnetic resonance (NMR) spectroscopy periodic table giving information the nuclear spins, etc., of the chemical elements, from the Bruker corporation website:
And, another:
The range of NMR active nuclei observable on a particular instrument is, in part, a function of the configuration of the spectrometer and the choice of available probes. The periodic tables below identify the nuclei that have resonance frequencies within the detection range of the Lake Forest College Inova and the EFT-60 NMR spectrometers.
The nuclei in red are I=1/2 and yield spectra with narrow, non-overlapping resonances. The nuclei in blue have quadrapolar moments and may give rise to broad or very broad resonances in their spectra.
| Year: 1998 | PT id = 246, Type = formulation spiral |
Wheel of Motion Periodic Table
The Wheel of Motion (WoM) representation of the periodic table of elements shows the periodic nature of the elements, as developed in the Reciprocal System of Physical Theory (RST).
It was originally developed by Douglas Bundy in 1998, a member of the International Society of Unified Science (ISUS).
| Year: 1998 | PT id = 376, Type = misc non-chem |
The Simpsons Periodic Table
A Periodic Table from the Simpsons... look closely and it is not quite as expected...

Lisa Gets an "A" Season Ten (1998-1999) - 23 Episodes [204-226] Episode 210 Original Airdate on FOX: 22-Nov-1998
Skinner: We can buy =real= periodic tables instead of these promotional ones from Oscar Meyer.
Krabappel: Who can tell me the atomic weight of bolognium?
Martin: Ooh ... delicious?
Krabappel: Correct. I would also accept snacktacular.
