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. There are also ten known ...
All isotopes ranging from 242 Cm to 248 Cm, as well as 250 Cm, undergo a self-sustaining nuclear chain reaction and thus in principle can be a nuclear fuel in a reactor. As in most transuranic elements, nuclear fission cross section is especially high for the odd-mass curium isotopes 243 Cm, 245 Cm and 247 Cm.
The colorless curium(III) chloride (CmCl 3) is made by reacting curium hydroxide (Cm(OH) 3) with anhydrous hydrogen chloride gas. It can be further turned into other halides such as curium(III) bromide (colorless to light green) and curium(III) iodide (colorless), by reacting it with the ammonia salt of the corresponding halide at temperatures ...
This is a list of radioactive nuclides (sometimes also called isotopes), ordered by half-life from shortest to longest, in seconds, minutes, hours, days and years. Current methods make it difficult to measure half-lives between approximately 10 −19 and 10 −10 seconds.
Theoretical element Applied: when element is theoretical (E119 and higher). No article "Isotopes of <element>": Header does not link; E119: Main isotopes of ununennium E121: Main isotopes of unbiunium Applied: E119, E120 do link, E121 and higher do not link. No isotopes known, Isobox does not exist: local input, per Infobox. For example:
However, 248 Cm can only be obtained in mg samples, so data collection for 248 Cm-containing compounds takes longer than that for compounds which predominantly contain other curium isotopes. [3] The data table below reflects a large variety of data collected specifically for curium sesquioxide, some of which is purely theoretical, but most of ...
So, element 105 was named dubnium, and element 106 was named seaborgium. The elements were placed in the periodic table’s seventh row, which is above the row of lanthanides and the row of actinides.
Curium(IV) oxide is an inorganic chemical compound of curium and oxygen with the chemical formula CmO 2. Since all isotopes of curium are man-made, the compound does not occur in nature. Since all isotopes of curium are man-made, the compound does not occur in nature.
