Pa/ A0165 History of science A2790 Properties of nuclei with 220 les AThe history of the discovery and naming of the three naturally occurring isotopes of element 91 is outlined in order to eliminate contradictions to be found in the literature. Information about the nineteen isotopes of ...
Isotopes of Elements- Isotopes refer to elements with nuclei having the same number of protons, but differing numbers of neutrons, so that the masses of contrasting isotopes differ by one to a few neutrons. To learn more about the Types, Examples, Physic
Discovery of the element with atomic number Z = 118 completing the 7th row of the periodic table (IUPAC Technical Report) The fourth IUPAC/IUPAP Joint Working Party (JWP) on the priority of claims to the discovery of new elements 113, 115, 117 and 118 has reviewed the relevant... Karol...
Shell architecture, element composition, and stable isotope signature of the giant deep-sea oyster Neopycnodonte zibrowii sp. n. from the NE Atlantic A conspicuous new deep-sea oyster, Neopycnodonte zibrowii sp. n., is described from the Azores Archipelago, where it thrives in 420 to >500...
In addition to protons, the atoms of nearly every element also contain neutrons. The mass of a neutron is almost identical to that of a proton. Both are formally given an atomic mass number, A, of 1. The simplest, commonest form of hydrogen has a nucleus that consists of a single prot...
(PhysOrg.com) -- A team of scientists at the U.S. Department of Energy's Lawrence Berkeley National Laboratory has detected six isotopes, never seen before, of the superheavy elements 104 through 114. Starting with the creation of a new isotope of the yet-to-be-named element 114, the ...
