By Eric Scerri

In 1913, English physicist Henry Moseley demonstrated a chic strategy for "counting" the weather according to atomic quantity, ranging them from hydrogen (#1) to uranium (#92). It quickly grew to become transparent, although, that seven components have been mysteriously lacking from the lineup--seven components unknown to technological know-how.

In his good researched and interesting narrative, Eric Scerri provides the exciting tales of those seven elements--protactinium, hafnium, rhenium, technetium, francium, astatine and promethium. The publication follows the historic order of discovery, approximately spanning the 2 international wars, starting with the isolation of protactinium in 1917 and finishing with that of promethium in 1945. for every point, Scerri lines the examine that preceded the invention, the pivotal experiments, the personalities of the chemists concerned, the chemical nature of the hot aspect, and its functions in technology and know-how. We examine for example that alloys of hafnium--whose identify derives from the Latin identify for Copenhagen (hafnia)--have the various optimum boiling issues on checklist and are used for the nozzles in rocket thrusters equivalent to the Apollo Lunar Modules. Scerri additionally tells the non-public stories of researchers overcoming nice stumbling blocks. We see how Lise Meitner and Otto Hahn--the pair who later proposed the idea of atomic fission--were suffering to isolate point ninety one while global warfare I intervened, Hahn used to be drafted into the German army's poison fuel unit, and Meitner used to be pressured to press on on my own opposed to daunting odds. The booklet concludes through analyzing how and the place the twenty-five new parts have taken their areas within the periodic desk within the final part century.

A story of 7 Elements paints a desirable photo of chemical research--the incorrect turns, neglected possibilities, bitterly disputed claims, serendipitous findings, accusations of dishonesty--all best ultimately to the fun of discovery.

Example text

By the time Lothar Meyer has written the manuscript for his book in 1862, he has produced a table of twenty-eight elements arranged in order of increasing atomic weight. An adjacent table containing a further twenty-two elements also appeared in the book, although these are not arranged according to atomic weight order. 29 Lothar Meyer publishes his table of twenty-eight elements for the first time in 1864 (fig. 11). 11 Lothar Meyer’s periodic system of 1864. J. Lothar Meyer, Die Moderne Theoriene der Chemie, Breslau, Wroklaw, 1864.

During this period Mendeleev was fortunate enough to attend the Karlsruhe conference of 1860, not because he was a prominent chemist but more because he happened to be at the right place at the right time. It was a pivotal conference at which the leading European scientists presented their views on atomic weights and the nature of atoms and molecules. Mendeleev quickly grasped the value of Cannizzaro’s ideas, as did Lothar Meyer, although Mendeleev’s conversion to using Cannizzaro’s atomic weights appears to have taken considerably more time than did Lothar Meyer’s.

Odling also notices that about half of the above cases include the first and third members of previously known triads. ” Here then is an example of a prediction made on the basis of a periodic system, although a rather tentative one that is not further developed to any extent. 6 Odling’s first table of differences. W. Odling, Quarterly Journal of Science, 1, 642–648, 1864. 14 A TA L E O F S E V E N E L E M E N T S by other intervals, such as 41 in this case. Thus it would appear that he recognizes the need to separate certain elements (those that would eventually become known as the transition metals) from the main body of the table.
