Until 1961 the Commission published reports in Comptes Rendus IUPAC.
Owing to that journal's limited circulation, the reports were reprinted
in most countries' principal chemical publications, e.g. by Journal
of the American Chemical Society, to which we here refer. After
1967 IUPAC published in Pure and Applied Chemistry which has
wider circulation and is in English, so that national journals tended
to abandon the practice of reprinting the Commission reports regularly.
For the elements of Table 1, the only remaining departures from current
nomenclature were:
i. in 1967, "cesium"
for Cs was used;
ii. several changes
in option or preference for calling element of symbol W (wolfram or
tungsten);
iii. since 1977, the
optional names of "stibium", "natrium", and "kalium"
for Sb, Na, and K, respectively, were so recognized; and
iv. since 1993, the
optional English names of aluminum and cesium for Al and Cs, respectively,
were so recognized.
b
"um" indicates that the name of aluminum was used and "ium"
indicates that the name of aluminium was used.
c
"ae" indicates that the spelling caesium was used and "e"
indicates that the spelling cesium was used.
d
Niobium was preferred in Europe, whereas columbium was used in the United
States.
e
Glucinum (symbol Gl) was commonly used for the element that is now universally
known as beryllium.
f
"c" indicates that the spelling lutecium was used and "t"
indicates that the spelling lutetium was used.
g
"ph" indicates that the spelling sulphur was used and "f"
indicates that the spelling sulfur was used.
h
Note that the element's symbol was always W; "tu" indicates
that the element was named tungsten; "wo"
indicates that the element was named wolfram.
i
"A" for argon, in the year's reports indicated; Sa
for samarium, and Yt for yttrium.
j
Published in prior year. This practice seemed desirable since many commercial
and scientific documents referenced the Commission-recommended atomic
weights. The delay, however, in recognizing reliable new results led
to the attempt after 1925 of publishing reports in the year indicated.
This aim was not often achieved.
