Charles Hinton, “The Fourth Dimension: A Language of Space”, 1906 was the topic of an earlier blog post.
Dmitri Mendeleev (1834 – 1907) Дмитрий Менделеев, “Principles of Chemistry”, 1868 also was the topic of an earlier blog post.
Here I present: Dmitri Mendeleev (1834 – 1907) Дмитрий Менделеев, “Principles of Chemistry”, 1868, PART TWO (2).

SUMMARY.
Natural Numbers versus Whole Numbers.
The main difference between natural numbers and whole numbers relates to the number 0 which is only a part of the set of whole numbers and is not present in the set of natural numbers.
The “Mendeleev table of 1868” presented for first time in history, that the elements from Hydrogen (H) to Uranium (U) were all that existed. “Mendeleev table of 1868” is shown BELOW.
Mendeleev leaves spaces in this tabulation for elements that were later discovered.
Antoine Lavoisier, “Elements of Chemistry, 1789 was a historic publication. Antoine Lavoisier made no attempt to “enumerate” his tabulation of elements. The idea of what number of elements is continuing today.
William Conyers Herring (1914-2009) was an American physicist who coined the term “Jellium” for element number zero. Herring is alluding to the “positive jelly” background and the typical metallic behavior it displays.
COMMENT
Jellium (0), Helium (2), Neon (10), Argon (18), Krypton (36), Xenon (54), Radon (86), and Oganesson (118) are not included in the “Mendeleev 1868” concept of elements.
Again, whole numbers are: 0, 1, 2, 3 … etcetera; and, natural numbers are: 1, 2, 3, 4 … etcetera.
