Curium is a synthetic chemical element; it has symbol Cm and atomic number 96. This transuranic actinide element was named after eminent scientists Marie and Pierre Curie, both known for their research on radioactivity. Curium was first intentionally made by the team of Glenn T. Seaborg, Ralph A. James, and Albert Ghiorso in 1944, using the ...
This list of chemical elements named after people includes elements named for people both directly and indirectly. Of the 118 elements, 19 are connected with the names of 20 people. 15 elements were named to honor 16 scientists (as curium honours both Marie and Pierre Curie). Four others have indirect connection to the names of non-scientists. [1]
Glenn T. Seaborg. Glenn Theodore Seaborg (/ ˈsiːbɔːrɡ / SEE-borg; April 19, 1912 – February 25, 1999) was an American chemist whose involvement in the synthesis, discovery and investigation of ten transuranium elements earned him a share of the 1951 Nobel Prize in Chemistry. [3] His work in this area also led to his development of the ...
americium, Am, named because it is an analog to europium, and so was named after the continent where it was first produced (1944). 96. curium, Cm, named after Pierre and Marie Curie, scientists who separated out the first radioactive elements (1944), as its lighter analog gadolinium was named after Johan Gadolin. 97.
Main article: List of chemical elements naming controversies. The naming of the synthetic elements dubnium and seaborgium generated a significant amount of controversy, referred to as the Transfermium Wars. The Americans wished to name element 105 hahnium, while the Russians preferred the name dubnium. The Americans also wished to name element ...
41 of the 118 known elements have names associated with, or specifically named for, places around the world or among astronomical objects. 32 of these have names tied to the places on Earth, and the other nine are named after to Solar System objects: helium for the Sun; tellurium for the Earth; selenium for the Moon; mercury (indirectly), uranium, neptunium and plutonium after their respective ...
The element with atomic number 96 was named curium (symbol Cm). [96] Three radioactive minerals are also named after the Curies: curite, sklodowskite, and cuprosklodowskite. [97] The Marie Skłodowska-Curie Actions fellowship program of the European Union for young scientists wishing to work in a foreign country [98]
Contents. Isotopes of curium. Curium (96 Cm) is an artificial element with an atomic number of 96. Because it is an artificial element, a standard atomic weight cannot be given, and it has no stable isotopes. The first isotope synthesized was 242 Cm in 1944, which has 146 neutrons. There are 19 known radioisotopes ranging from 233 Cm to 251 Cm.
