Fajans rule

Kazimierz Fajans Kasimir Fajans in many American publications; 27 May — 18 May was a Polish-American physical chemist, a pioneer in the science of radioactivity and the co-discoverer of chemical element protactinium. In he was awarded his PhD for research into the stereoselective synthesis of chiral compounds. In Fajans took a job at the laboratory of Ernest Rutherford in Manchester , where the nucleus was discovered.

He then returned to Germany, where he became an assistant and subsequently assistant professor at the Technical University of Karlsruhe , researching radioactivity. In he left Germany due to escalating Nazi persecution. He stayed for a while in Cambridge and then moved to the University of Michigan where he worked until his demise.

In he became an honorary member of the Polish Chemical Society.

Fajans retired at age of seventy but never stopped working. He died May 18, , in Ann Arbor, Michigan. Fajans worked with Henry G. Moseley at the laboratory of Ernest Rutherford researching properties of the radioactive rows of the periodic table. He identified the half-lives of the uranium - actinium row and thorium nuclides. He discovered the phenomenon of the electrochemical branching of the radioactive rows.

Afterwards Fajans worked on the electrochemical properties of elements as a result of the radioactive changes, and he formulated the law of the radioactive shifts which was later named the radioactive displacement law of Fajans and Soddy Frederick Soddy received the Nobel Prize in chemistry in for his isotopic research.

It is very significant for separation and purification of radioactive substances found in the smallest number. In , Fajans began researching the structure of crystals by thermochemical and refractometric methods. The co-relation of Born, Fajans and Haber is a basic thermochemical rule.
