Ramsay William

Raman left Calcutta in 1933 to become the director of the Indian Institute of Science, in Bangalore, where he remained until 1948. He continued his research on optical and electromechanical phenomena but also worked on a wide range of problems that reflected his fascination with the natural world—diamonds, seashells, and the coloration of flowers and feathers. In 1948 he established the Raman Research Institute in Bangalore, where he continued to carry out research until almost the end of his life. He died on November 21, 1970. see also Spectroscopy.

William Ramsay, the only child of civil engineer and businessman William Ramsay and his wife Catherine, was born on October 2, 1852, in Glasgow, Scotland. Despite the scientific background of his family, he was expected to study for the ministry. He completed his secondary education at the Glasgow Academy and in 1866 entered the University of Glasgow, where he

The principal isotope of argon is °Ar (99.6% abundance) it has two other stable isotopes, Ar (0.3%) and Ar (0.1%). Argon-40 is formed by jS-decay of the long-lived potassium isotope see also Noble Gases Ramsay, William Strutt, John. 

Although a noble gas, krypton is not entirely unreactive. One krypton compmmd, krypton difluoride (KrF2), is commercially available in small quantities. SEE ALSO Gases Noble Gases Ramsay, William Travers, Morris. 

Neon is produced within stars during nucleosynthesis. It has three stable isotopes, of which neon-20 is the most abundant (90.5%). see also Gases Noble Gases Ramsay, William Travers, Morris. 

In 1962 the first chemical noble gas compound, formulated as XePtFg, was synthesized by Neil Bartlett. This result spurred intense research activity and led to the discovery of numerous xenon and krypton compounds. In 2000 the formation of the first argon compound, argon fluorohydride (HArF), was reported by Leonid Khriachtchev and colleagues, see also Argon Cavendish, Henry Helium Krypton Neon Ramsay, William Ruthereord, Ernest Soddy, Frederick Strutt, John Xenon.

In 1914 Soddy assumed the chair of chemistry at Aberdeen University, Scotland, but his teaching and research were largely interrupted by World War I. In 1919 he was appointed to the Lee Chair of Chemistry at Oxford University, a post he held until his retirement in 1937. In 1921 Soddy received the Nobel Prize in chemistry for his contributions to our knowledge of the chemistry of radioactive substances, and his investigations into the origin and nature of isotopes. He died in Brighton, England, on September 22, 1956. SEE ALSO Ramsay, William Rutherford, Ernest.
