Lawrencium was named in honor of the chemist of what nationality?
Lawrencium Lawrencium is a synthetic chemical element with symbol Lr (formerly Lw) and atomic number 103. It is named in honor of Ernest Lawrence, inventor of the cyclotron, a device that was used to discover many artificial radioactive elements. A radioactive metal, lawrencium is the eleventh transuranic element and is also the final member of the actinide series. Like all elements with atomic number over 100, lawrencium can only be produced in particle accelerators by bombarding lighter elements with charged particles. Twelve isotopes of lawrencium are currently known; the most stable is Lr with a half-life of 11 hours, but the shorter-lived Lr (half-life 2.7 minutes) is most commonly used in chemistry because it can be produced on a larger scale.
Georg Lunge Georg Lunge (15 September 1839 – 3 January 1923) was a German chemist born in Breslau. He studied at Heidelberg (under Robert Bunsen) and Breslau, graduating at the latter university in 1859, for the work with Ferdinand Cohn. Turning his attention to technical chemistry, he became chemist at several works both in Germany and England, and in 1876 he was appointed professor of technical chemistry at ETH Zurich. Lunge's original contributions cover a very wide field, dealing both with technical processes and analysis. In addition, he was a voluminous writer, enriching scientific literature with many standard works. His treatises "Coal Tar and Ammonia", "Destillation des Steinkohlentheers" and "Sulphuric Acid and Alkali", established his position as the highest authority on these subjects, while the "Chemische-technische Untersuchungs-Methoden", to which he contributed, testified to his researches in technical analysis. His jubilee was celebrated in Zurich on 15 September 1909. He died in Zurich on 3 January 1923.
