Cur (Cm), synthetic chemical element of the act element of the periodic table, atomic number 96. The unknown nature, cur (as isotope cur-242), was discovered by the American chemist Glenn T at the University of Chicago (summer of 1944). Seaborg, Ralph A. James, Albert Ghiorso is a sample of the strontium isotope 钚 239 in which cesium ions (alpha particles) collide in a 152 cm (60 inch) cyclotron at the University of California, Berkeley. This is the third uranium element that was discovered. This element was named after French physicists Pierre and Mary Curie.
Cur is a metal of silver. Its isotopes are all radioactive. In chemical studies cur - 242 (163 - day half life) was replaced by cur - 244 (18.1 year half - life) and the long - lived isotope cur - 248. Neutron irradiation Cur shows a normal + 3 oxidation state such as very weak yellow Cm 3+ ion, trioxide Cm 2 O 3, trihalide in aqueous solution, and other ternary acting elements and chemistry It is similar. The +4 oxidation state occurs in the carbon dioxide CmO 2 and the Cm 4 + ion complexes with the fluoride ion.
As of November 2018, 118 chemical elements have been identified. A chemical element or element is an atomic species (that is, the same atomic number or Z) having the same number of protons in its nucleus. Hence, elements can be listed by the number of protons in the atoms of each element listed below.
Transmutation is the conversion of one chemical element or isotope to another chemical element. Because the element (or isotope) is defined by its atom, the number of protons (and neutrons) in the nucleus, transmutation occurs as the number of protons or neutrons in the nucleus changes. Natural metamorphosis of past star nuclear synthesis has created the majority of the most heavy chemical elements in the known universe and continues to date and continues to date with the most common elements of the universe, including helium, oxygen and carbon It is producing. Most stars undergo metamorphism through a fusion reaction including hydrogen and helium, and larger stars can also fuse heavier elements to iron later in evolution.
The first task is to find a way to manage and effectively execute the LENR conversion of chemical elements. In other words, converting low value chemical elements to valuable elements. The results of the method analysis which is promising for industrial application proved that the microbiological method of chemical element metamorphism is not promising. In biological environments, transformation is uncontrollable and will not produce significant consequences within the next 15 to 20 years.
