British Reception of Periodicity
The discovery of periodicity in the properties of the elements and its connection to their atomic weights is one of the most important advances in nineteenth-century chemistry. This chapter will consider the tables of John Newlands (1837–1898) and William Odling (1829–1921), which preceded that of Dmitrii Ivanovich Mendeleev (1834–1907). Mendeleev’s table was published in 1869, prior to his being aware of the UK precedents of his tabulation. The major portion of this chapter will extend the ideas advanced by Stephen Brush in The Reception of Mendeleev’s Periodic Law in America and Britain but will restrict itself to the dissemination of the periodicity concept within the United Kingdom. This will be monitored by recording its appearances in textbooks and examination papers, and in a wider context, by extracting data from Google Books. The periodic table has a rich history since its inception. It has evolved into many shapes, and indeed dimensions, yet retaining its essential periodic underpinning. In the United Kingdom it is seen as a “table,” whereas the French prefer “classification” and the Germans and Russians “system.” Mendeleev himself referred to his periodic law in his Faraday Lecture and never used the term “table,” thus it is ironic that his fame is linked to words that he appears never to have uttered. The arrangement of the elements in rows and columns is seen as a table, but why label it periodic? A related, more familiar word to non-chemists is periodical, normally referring to a magazine that appears at regular time intervals. Google Books is a powerful modern tool for investigating the usage of selected words or phrases over selected time intervals. The writer chose to use its advanced search for books in the English language. This meant that sources other than British, notably North American, are also included but the observed patterns are probably true for British books. The data compare the number of times the terms periodic table, periodic law, periodic classification, and periodic acid occurred in five-year intervals between 1870 and 1919.
