    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.

    en.wikipedia.org/wiki/Curium

    If it gets into the human body, curium accumulates in bones, lungs, and liver, where it promotes cancer. All known isotopes of curium are radioactive and have small critical mass for a nuclear chain reaction. The most stable isotope, 247 Cm, has a half-life of 15.6 million years; the longest-lived curium isotopes predominantly emit alpha particles.

    Water (H2O) is a polar inorganic compound that is at room temperature a tasteless and odorless liquid, which is nearly colorless apart from an inherent hint of blue. It is by far the most studied chemical compound [ 20 ] and is described as the "universal solvent " [ 21 ] and the "solvent of life". [ 22 ]

    en.wikipedia.org/wiki/Isotope

    Isotope analysis is the determination of isotopic signature, the relative abundances of isotopes of a given element in a particular sample. Isotope analysis is frequently done by isotope ratio mass spectrometry. For biogenic substances in particular, significant variations of isotopes of C, N, and O can occur.

    en.wikipedia.org/wiki/Bioarchaeology

    Bioarchaeology (osteoarchaeology, osteology or palaeo-osteology[ 1 ]) in Europe describes the study of biological remains from archaeological sites. In the United States it is the scientific study of human remains from archaeological sites. The term was minted by British archaeologist Grahame Clark who, in 1972, defined it as the study of ...

    The darker more stable isotope region departs from the line of protons (Z) = neutrons (N), as the element number Z becomes larger. This is a list of chemical elements by the stability of their isotopes. Of the first 82 elements in the periodic table, 80 have isotopes considered to be stable. [1] Overall, there are 251 known stable isotopes in ...
