Isotope electrons in the neutral (non-ionized) atom. Each atomic number identifies a specific element, but not the isotope; an atom of a given element may have a wide range in its number of neutrons. The number of nucleons (both protons and neutrons) in the nucleus is the atom's mass number, and each isotope of a given element has a different mass number. For example, carbon-12, carbon-13 and carbon-14 are three isotopes of the element carbon with mass numbers 12, 13 and 14 respectively. The atomic number of carbon is 6, which means that every carbon atom has 6 protons, so that
Isotopes of moscovium channel with the highest expected yield is given. MD = multi-dimensional; DNS = Di-nuclear system; σ = cross section Isotopes of moscovium Moscovium (Mc) is a synthetic element, and thus a standard atomic weight cannot be given. Like all synthetic elements, it has no stable isotopes. The first isotope to be synthesized was Mc in 2004. There are four known radioisotopes from Mc to Mc. The longest-lived isotope is Mc with a half-life of 0.8 seconds. The table below contains various combinations of targets and projectiles which could be used to form compound nuclei with Z=115. Each entry is a
