Abstract: This Essay projects the spark of genius of Mende-
leev,whose efforts led to the effective formulation of the
periodic table,whichhas placed the entire world of chemical
matter on apalm. The periodic table gave rise to acentral
paradigm, which did for chemistry what Newton had done for
physics and Darwin for biology.Subsequently the Essay
recounts the popularization of the Periodic Table through
literature by Primo Levi, Oliver Sacks and others,and through
music and art by composers and artists,such as Jerry Feldman,
the King Crimson band, TomLehrer,and George Brecht, Blair
Bradshaw,EugHnia Balcells,etc.
1. Introduction
Theheated debates of chemists during the 19th century
formed the background for MendeleevQsperiodic table.[1–3]
Figure 1shows the explosion of information on “chemical
elements” in the post-LavoisierQsera.[4] Thedefinition of
a“simple body” by Lavoisier[5a] provided the chemists with an
effective manner of discovering new elementary materials.
These were materials that could not be decomposed into
simpler ones within the technical means of agiven time.This
definition has led to the discovery of many elements,[6] and
suddenly there seemed to be too many… Thechemists feel
being cast out of Paradise:they start to yearn for the simple
world of 4-elements (air, earth, fire and water) and the
quintessence (protyle).[2b, 3c,5b] However,assoon as the
recognition sets in that this paradise is gone forever,the next
best is to find “orders and rules” in the information.
Amajor step towards order was the atomic hypothesis by
Dalton (1803).[5c] John Dalton (Figure 2a)argued that the
mass of matter is quantized as atomic particles.Hecreated
calculus for estimating atomic weights (AW), and he defined
molecular-chemical-identity in terms of atomic combinations.
Some chemists like Wurtz, Laurent, Gerhardt (Figure 2b),
etc.,accepted the atomic postulate.Others like the physicist
Ernst Mach, and the chemists Berthelot and Dumas (Fig-
ure 2c)rejected it.[7] DaltonQscalculus was imperfect and
generated different AW values for the same element. This
brought about too much confusion. So much so that Dumas
declared (in 1837) “If Iwere master Iwould efface the word
atom from science”.
Then came the Karlsruhe conference in 1860. This was the
1st symposium of chemistry.During the symposium, Canni-
zzaro (Figure 3a)used the Avogadro hypothesis [that equal
volumes of gases involve the same number of molecules,and
that “simple bodies” like hydrogen and oxygen involve union
of the same atoms][2a,5c,7] and generated aset of consistent AW
values based on ascale with H =1au. He defined the “mole”
and the volume of mole,aswell as valence;the latter as the
ratio of the AW to the combining weight (e.g., for oxygen
