WebIn the last few years, the modeling of asymptotic giant branch (AGB) stars has been much investigated, both focusing on nucleosynthesis and stellar evolution aspects. Recent advances in the input physics required for stellar computations made it possible to construct more accurate evolutionary models, which are an essential tool to interpret the wealth of … WebYou can get the atom to be stable/unstable by adjusting the number of neutrons Adding electrons will change it from a +ion to neutral atom, to ion depending on how many electrons you add Adding electrons you can only add 2 to the first orbital and 8 to the second . b) What particle(s) are found in the center of the ...
WebThe number of protons in an atom is known as the Atomic Number, which is how the periodic table is organized (they are listed in order of atomic number from left to right). The Mass Number describes the total number of protons and neutrons in the nucleus. An atom in its typical state will not have a charge, as the positive particles (protons) balanced out … WebQuestion: The element rhenium (Re) has two naturally occurring isotopes, ^185Re and ^187Re. with an average atomic mass of 186.207 amu.

Web24 jan. 2024 · But most of the protons in a neutron star convert into neutrons—neutron stars are made up of about 95 percent neutrons. When protons convert to neutrons, they release ubiquitous particles called neutrinos. Neutron stars are made in supernova explosions which are giant neutrino factories.
