A paper describing the discovery has been accepted for publication in Physical Review Letters.rnA team led by Yuri Oganessian of the Joint Institute for Nuclear Research in Dubna, Russia, created the new element by smashing calcium-48 - an isotope with 20 protons and 28 neutrons - and ...

A chemical element is a substance which cannot be decomposed or resolved into simpler substances by ordinary chemical means. Altogether 105 elements are known. Each element consists of one or more atoms with the same number of protons in the nucleus and electrons outside the nucleus. Not all at...
The nuclear notation of an atom or an ion shows the number of protons, the number of neutrons, and sometimes, the number of electrons. However, these are not presented as they are because they are encoded as the mass number and the atomic number. With this, it is easier ...
the protons and neutrons in a nucleus fill ‘shells’, similar to electrons in atoms. Isotopes with filled shells should prove far more stable. The aim was to hit an isotope with a ‘magic number’ of protons or neutrons. ‘With these magic numbers we have more binding forces,’ Oganessia...
With further analysis, Normand inferred that this error rate must have been due to atmospheric neutrons. In five Nite Hawk computers, Normand found the error rate of DRAM to be around 2.3 milliFIT/bit. He also looked at a CRAY YMP-8's SRAM memory system log and found the error rate to...
The mass number represents the number of protons plus neutrons in the nucleus of an atom of the element. The number of protons determines the element, but the number of neutrons in the atom of any one element can vary. Each variation is an isotope. Five radioactive isotopes of silicon ...
existing nuclide at each step was transformed into a new nuclide after losing two protons and two neutrons, with each chain terminating in nuclear fission. The former chain involved three alpha decays and occurred five times, whereas the latter consisted of six alpha decays and took place just ...
